NOTE: "AR" = Action Required. -------------------------------- MINUTES ------------------------------------- INTRODUCTIONS The European IBIS Summit Meeting was held in Paris, France the day after the Design Automation and Testing in Europe conference (DATE 2000) at the Concorde La Fayette Hotel. Cadence Design, Incases Engineering, Innoveda (formerly Viewlogic Systems), Mentor Graphics served as co-sponsors. About 26 people representing 12 organizations participated. Bob Ross welcomed the participants and noted that questions and interactive discussion was encouraged. Everybody introduced himself. Semiconductor vendors, EDA vendors and users (along with an individual from a research institute) were all represented. (Also, thanks to Karine Loudet and Francoise Lindecker of Mentor Graphics for producing the posters and handling the administrative and registration details.) All of the presentations and meeting documentation will be uploaded at http://www.eda.org/pub/ibis/summits/mar00/ The notes below give some off the content and discussion. SIEMENS ICN I/O MODEL SPECIFICATION (Terms of Delivery for I/O Models of Digital Integrated Circuits V50004-Y1-T210-*-7625 Revision Feb.08.2000) Gerald Bannert, Siemens AG Gerald Bannert passed around the above draft specification. It includes material presented at previous European IBIS Summit meetings. Siemens prefers IBIS models. However, Gerald finds that IBIS Models from manufacturers are insufficient for Siemens needs for several reasons: They use older than Version 3.2 revisions of IBIS. Useful options are missing, and model quality is not good. Technical IBIS content and parameter definition in IBIS is insufficient, incorrect, or difficult to understand. Some additional parameters are needed for the internal Logical Design Rule Checker (LDRC) tool. The specification contents are: Part 1: Quality, references, data consistency, transaction complete. Part 2: Technical supplement/changes to IBIS Version 3.2 Part 3: Additional parameter requests. The specification is being reviewed internally and is also being distributed to major semiconductor vendors. Additions to the document are expected for improved accuracy, EMI, HF, and SSO. Vendors supplying the added information of Part 3 may become preferred vendors. Gerald then gave an overview outline of the content (summarized here): Superordinate, general and technical requirements for delivery (16 pages) General introductory and scope material Guarantee, model changes (MCN) validity for models tracking device changes General requirements for IBIS models - application, data consistency, availability and definition of typ, min, and max parameters for process, Tj, and Vcc Requirements for other formats (underway) Plus parameter requirements Annex 1 (27 pages) Technical definitions (e.g., overshoot, Vdiff) Limits of interest Measurement and simulation conditions (e.g., SSO, Tj, loads) IBIS points of table entries Siemens ICN options Annex 2 (18 pages) File structure and relationship of .ibs and .sie (for Siemens) Technical data definition (e.g., fail safe, Vsource, slew rate, I/O type Functional pin mapping (e.g., clock, data) Gerald discussed a number of these points. The IBIS Version 3.2 specification only gives general guidelines for entering typ, min, and max parameters. The Siemens document gives more detailed definitions. The typical model should have typical process conditions within +/- 0.5 sigma. The standard JEDEC voltages (12, 5, 3.3, 2.5, 1.8, 1.5, and 1.3) need to be specified. The typical junction temperature condition should correspond to about 40 degrees C ambient. The min and max process parameters should be approximately the 2.3 sigma points. The voltages should be +/- 5 percent. The junctions temperature range should be 0 degrees C to 110 degrees C. Some existing IBIS models from semiconductor vendors have too large of a range to be useful in real designs. Gerald elaborated on a needed Vdiff_max subparameter for differential pins and how they relate to S_overshoot and D_overshoot entries. Furthermore, he illustrated typ, min, and maximum thresholds and their relationship to a Vth threshold voltage. Bob Ross commented later that pending BIRD62.6 may cover much, if not all of these details. The S_overshoot and D_overshoot parameters are defined for currents that are transformed into voltages for a variety of clamping conditions that are appropriate for the technology. Clamping conditions range from no clamp, leakage currents, regular clamp and zener clamp. Some recommendations are provided for assuring that table data points are spaced for maximum accuracy. The changes in slow need to be with 3 to 4 percent of the previous slope. Load conditions for [Rising Waveform] and [Falling Waveform] are given. Also, if the overshoot exceeds 10 percent, [Driver Schedule] is recommended. A number of topics are not covered in this draft, but are expected to be included in the future. The include [Driver Schedule], [TTgnd], [TTpower], terminations and passive series elements, [Series MOSFET], [Submodel]s, .pkg and .ebd formats. Gerald introduced additional parameters needed for the internal Siemens tool called Logical Design Rule Checking (LDRC). This tool performs design checks for connectivity, reasonableness, power, etc. that are normally not included in EDA tools. For example, the keyword [SI_add_pin_info] documents more information for each pin: clock (clock, latch, asynchronous Set/Reset inputs) data (data/address inputs, synchronous Set/Reset inputs) logic (buffer and other combinational inputs) static (enable inputs, control inputs) Vbb for ECL) vsource (built in voltage source such as analog (crystal, R/Cext, OpAmp inputs and outputs) pwr_gnd (Vcc, Gnd, Vee) dnc (physically exiting, but not connected nnc (pin does not exist) unknown (assignment to one of the above not possible) output (all outputs) Gerald discussed the [SI_add_cell_information] keyword. It would give ioh_max, ioh_min, bushold min and max currents, technology, and leakage current limits. Furthermore it would define input slew rate limits. Gerald answered in response to a question from Tom Dagostino that the input slew rate also covered reflected wave switching. Technology information relates to actual driver application such as bus driver, board and back plane application, shortest cable connections. Also hot insertion rules are indicated, if allowed. Also, EOS robustness is of concern. The [SI_analog_model] keyword gives c_subst, r_subst_ and v_substr values. Gerald noted that Siemens simulates 100 percent of the boards and 100 percent of the nets. During and after the presentation, number of these items were discussed. Werner Rissiek commented that the additions could be pushed through the IBIS committee. TIPS AND TRICKS FOR CREATING IBIS MODELS Cary Mandel, Innoveda (formerly Viewlogic Systems) Cary Mandel commented that Jon Powell of Innoveda Consulting Services wrote this. The material was based on experiences producing IBIS models from HSPICE and testing them on an Innoveda simulator. The overall test setup is part of an internal Virtual Modeling Lab (VML) which allows programming of extraction and test conditions. Cary showed the preferred 50 ohms to ground and 50 ohms to Vcc loads for extracting V-T tables. Package parasitics need to be removed. Cary noted that Spice options need to be set for proper DC convergence, and that the time response needs to be long enough to reach the final value. Sometimes the IBIS 100 point limit makes it difficult to have high accuracy for typ, min and max columns simultaneously. Cary also noted that the input signal should be fast enough so that does not slow down the output response. To do the quality assurance (QA) comparisons, a mid point voltage needs to be selected to synchronize the rising and falling edges. Then results can be overlayed and compared. To further test the model, comparisons using other test conditions such as 50 pF to ground, a transmission line load, and a full package test case could be added. Cary listed some common problems: Simulation time does not allow waveform to reach full high or low. Spice model does not behave well at the corners. Spice models need special control options to converge. Spice diode models create unlikely amounts of current. QA simulation does not reproduce some Spice features. The difficulties with IBIS are: 100 point limit can create difficulties in fitting large typ, min, and max I-V and V-T tables. Careful linearization may be needed. Typ, Min and Max may not describe full range of corners desired. The LC package model may be insufficient. The IBIS Version 3.2 T-line model is needed in many cases including RAMBUS modeling. The transition time (ramp) is not very useful for rise time controlled and many high speed advanced drivers. Cary showed an example of a QA simulation where a model with V-T waveforms overlayed the source data compared to the one based on ramp data with a significant time mismatch. Tom Dagostino commented on his experiences measuring diode currents and suggested a limit in the order of 100 mA to 1 A. Default generic diodes were suggested when the Spice model contains unrealistic "ideal diodes". IBIS ACCURACY STUDY Sherif Hammad, Mentor Graphics Sherif Hammad introduced some metrics for comparing model simulation results with initial time waveform extractions. The first two dealt with delay comparison and alignment and the last three dealt with accuracy comparisons: CCPV - Cross-Correlation Peak Value CCTO - Cross-Correlation Time Offset AAD - Average Absolute Difference in V AAD (%) - Average Absolute Difference in percentage COM (%) - Curve Overlay Metric (from the Accuracy Specification) Then Sherif illustrated the metrics with IBIS Models constructed using four waveforms (50 ohms to ground and Vcc), two waveforms (50 ohms to ground for rising and 50 ohms to Vcc for falling), and then ramp specification for the same conditions. The illustrations and metrics showed nearly perfect correlation (99.8%) for the four waveform cases, and worse correlation for the two waveform (96.0% to 98.2%) and ramp (97.5%) cases. The delay metrics showed nearly zero shift for the best four waveform cases, and up to 100 picoseconds for some other cases. Then Sherif illustrated testing the robustness of the four waveform based model using a 50 ohm to Vcc/2 load (99.5%) and 30 ohm to ground load (99.2%). The delay shift was up to 10 picoseconds. This was just a sampling of tests. Lionel Dreux commented that he needed to match IBIS Model loads to the actual net loads for accuracy. After some clarification discussion, we determined that the best model was still based on resistive loads (not timing) loads and that Sherif's results showed good accuracy. However, Fabrice Boissiere and others commented that different technologies might require different loads consistent with their typical operating conditions (for example, GTL uses 25 ohms to 1.0 V). TC93WG6 EMC/EMI IC MODEL STANDARDIZATION REPORT Jean-Claude Perrin & Jean-Yves Oberle, Texas Instruments Jean-Claude Perrin, chair of IEC TC93WG6 introduced the EMC/EMI simulation needs: IC manufacturers need to take into account EMC constraints in IC design and need to simulate EMC behavior and contribution PCB manufacturers need to comply with EMC requirements and simulate EMC phenomena on PCBs. Jean-Claude summarized the history of the committee. It began work in 1994, introduced IEC 93/67 NP in June 1997, held an international task force meeting in 1998, and held a recent experts meeting on March 30, 2000. The main conclusion is that IBIS Models can be enhanced to do top-level EMI simulation. IBIS does not take into account: I/O noise due to internal activity Fast transitions of current through power supplies Direct electromagnetic emission from ICs At this time the task group is concerned with emission and not susceptibility. A model for behavioral simulation was shown. It consists of: Zp and Ip impedance current and noise generator across the Vdd/Vss supplies, Sa and Ga equivalent noise generator/antenna responsible for external hf noise emission, Hx(F) transfer functions between internal generator and other input/output pins. The active blocks are: Core power supplies Peripheral (I/O) power supplies Clock signals activity Package A draft proposal for IBIS format extension consists of these new keywords: [Core Current] Instantaneous current consumption [Pad Current] Instantaneous current consumption [Die Size] Width and length of the die [Clock Frequency] Clock frequencies of the device [Pad Clock] List of pads connected to one of the clocks The proposal is still in draft form and has not been made available outside of the committee. Jean-Claude outlined some of the remaining steps. IEC and the IBIS Open Forum would look at the document and assist in model validation and vote on the document. The document needs to show: Model definition Tem cell current measurement IBIS EMC specific files Jean-Claude proposes that EDA vendors assist in validating the model adapting their tools to do simulation of power supply and clock signals. Jean-Yves Oberle showed measurements of the electric field radiated by an IC for two orientations shifted 90 degrees apart. Jean-Yves compared the measurements to simulation results. The shapes showed excellent agreement, but noted that measurement setup variables are hard to control, and the simulation used approximations. Jean-Yves highlighted areas where the differences were 15 dB to 25 dB, still not bad for this type of comparison. A number of technical question and suggestions were discussed. Jean-Yves explained that the simulation was performed using Maxwell equations and Spice. Werner Rissiek liked the model. Jean-Claude noted that a different group, IEC TC47 is working on measurement standards. Tom Dagostino asked how long the simulation took and suggested a simpler test case, such as a wire, when the response was about one day. Based on his experiences, Lionel Dreux suggested that closer simulations results might be achieved by also considering magnetic sources. This type of simulation needs to include the decoupling network on PCBs. Bob Ross commented that the document needs to be released for public distribution in order for it to proceed. Jean-Claude intends to work on the refinements and then have it made available to the IBIS Open Forum. Later in the meeting Bob stated that the draft document was structured as a Section 10 addition to IBIS Version 3.2. This might be a good way to go since IBIS Version 3.2 is stable. (Bob had considered having this as a separate stand-alone standard to make it easier to ratify.) IBIS FUTURE ACTIVITIES Bob Ross, Mentor Graphics Bob Ross moved his presentation to the time slot before lunch. Bob gave an overview of the meeting today. It deals with current and future specification requirements and clarification, modeling tips and accuracy studies. It also deals with potential future activities including the EMI/EMC modeling, behavioral receiver modeling, and the current IBIS development activities. Bob gave a status update showing that IBIS Version 3.2 is now an official ANSI/EIA-656A standard and is approved as IEC 62014-1 and is awaiting publication. The ibischk3.2.5 parser has been released, but some bugs have been discovered and need to be fixed. The IBIS Users group has released the IBIS Connector Specification to the IBIS Open Forum Committee and also may be resuming work on the Accuracy Specification. The Accuracy Specification is now targeted to be a handbook. The IBIS Open Forum chose not to produce a Spice to IBIS for IBIS Version 3.2 since commercial vendors are also interested in doing this. The main activities of the IBIS Open Forum are The Connector Specification IBIS Version 4.0 IBIS-X for the future The IBIS Open Forum continues to track other activities: TC93WG6 EMC/EMI EIAJ IMIC Specification JEDEC activities Bob summarized some technical aspects of the Connector Specification and noted that after a syntax review, a formal review leading to a ratification vote will be conducted. The Specification is expected to be ratified around mid 2000 as a Version 1.0 document and then a syntax checker and parser development project is expected to be initiated. The IBIS Version 4.0 update is driven by some immediate needs by the JEDEC for DDR memories and current SSTL-3 technologies. BIRD62.6 is expected to be ratified for better input specification detail. Dr. Bernhard Unger's solution for simultaneous switching noise (SSN) modeling is of great interest. Other open BIRDs and specification suggestions will be examined. Perhaps a few other ideas such as AVC modeling might be proposed and considered. This upgrade is expected to be ratified sometime during 2000. The IBIS-X activity is really a name for a group of possible proposals that relate to longer term needs for IBIS. Many needs have been reported on the IBIS reflector and at several of the recent IBIS Summit Meetings. The latest meeting held January 31, 2000 contained several presentations that covered IBIS-X, "BIRDxxx", macro language, application programmable interface and other ideas. Bob noted from one presentation that there was interest in scalability (one node to many nodes), flexible representation (current IBIS elements, controlled voltage and current sources, S-parameters, etc.), and nodal representation similar to Spice. Bob also reported that the IBIS-X proposal might be similar and support much of IBIS. It might also support functional port definitions and also some Spice-like nodal constructs. This would allow faster production of models as technological advances occur. (Later, Bob noted that Werner Rissiek had suggested that IBIS-X may be moving towards becoming a modeling language (such as Spice) as opposed to a format for model data. Bob reported that several people planned to meet in Oregon on Thursday, March 30, 2000 to start formulating a consensus proposal. Bob expected that while we may see the proposal shortly, we may take a year or two for actual review and ratification as a separate standard. BEHAVIORAL RECEIVER MODELING Patrick Dos Santos, Cadence Design After a delicious buffet lunch hosted by Cadence Design, Patrick Dos Santos indicated that the Behavioral Receiver Modeling presentation was authored by Donald Telian and had also been given at the January 31, 2000 IBIS Summit Meeting. Patrick showed the evolution of design methodology: Use terminations (mid-1980s) Driver scaling and tuning (early 1990s leading to IBIS and to tools for topology optimization) Now - more detailed receiver modeling Receiver modeling allows optimization: What switching functions are needed? What type of pulses are to be rejected? What sort of propagation characteristics will work? What voltages should this all operate at? The best approach is to use a nodal behavioral description because it allows modeling of a receiver's characteristics and also is easily adaptable to arbitrary behaviors. Patrick noted that nodal based receivers can be derived from measurement or simulation. The behavioral receiver contains these blocks: #1: Low Pas filter - reject certain pulse spikes #2: Switching Function - receivers basic transfer function #5: Intrinsic Delay - delay for fasted edge #3: Edge Rate Detection - derivative of input signal affects delay #4: Delay Adder - dynamically adjusts circuit delay based on #3 Its implementation needs these features: Nodal language G (VCC) and E (VCVS) sources (PWL, Equation driven with derivatives, even driven and time-controlled as well) Real-time adaptive delay line Subcircuiting nesting and random node printing Based on 242 difficult test cases, the simulation results showed an average difference of 19 pS (standard deviation of 14 pS). Simulation times were slightly slower, but still in the same order of magnitude as Spice simulations. Many of the models had additional proprietary elements, slowing the simulation. Gerald Bannert asked whether input impedance details can be accurately modeled. Patrick responded yes since input elements can be added to any level of detail using standard nodal syntax. Also differential inputs and clamping diodes can be modeled. Lionel Dreux commented that the approach might be extended for field coupling to a PCB. It might be used for susceptibility. Upon questioning, Patrick stated that non-linear effects are included. Werner Rissiek commented that the IBIS still has its place since it is scalable to any accuracy needed. For example, the IBIS model can be as simple or detailed as appropriate for the analysis. Patrick stated that the behavioral receiver model could be scalable. CLOSE OF MEETING Bob Ross provided some more detail on the pending Connector Specification regarding using cascaded sections to configure the connector for different sockets and different board thicknesses (for the edge card side of an edge card connector). Bob summarized that along with current activities dealing with the Connector Specification, IBIS Version 4.0 definition and IBIS-X definition, the IBIS Open Forum could also be dealing with more IBIS Version 3.2 clarifications based on the Siemens requirements, possible electronic data sheet requirements needed by Siemens, and possibly an EMI Section 10 addition to IBIS Version 3.2. Bob again thanked the participants for their contributions and the co-sponsors. Several participants commented on the amount of interesting material presented at this meeting and supported IBIS as an appropriate level for the potential extensions. NEXT MEETING: The next teleconference meeting will be on Friday, April 14, 2000 from 8:00 AM to 10:00 AM. BIRD62.6 will be scheduled for voting. ============================================================================== NOTES IBIS CHAIR: Bob Ross (503) 685-0732, Fax (503) 685-4897 bob_ross@mentor.com Modeling Engineer, Mentor Graphics 8005 S.W.

A list of reported bugs will be maintained on vhdl.org. ****************************************************************************** PARSER VERSION NUMBER: Found in IBISCHK3 V3.2.1 built for DOS. Confirmed in IBIS_CHK2 V2.1.17 for DOS. PLATFORM (SPARC, HP700, PC, etc.): PC OS AND VERSION: Windows NT Server 4.0 (Build 1381: Service Pack 4) REPORTED BY: Matthew Flora HyperLynx (425) 869-2320 mbflora@hyperlynx.com DATE: 12 Jan 1999 27 Oct 1999 - Amended DESCRIPTION OF BUG: The parser does not report an error if an output buffer has no V/I tables (and therefore is not an output). Perhaps the parser should test for the presence of certain V/I tables for other Model_types as well. AMENDMENT: After an IBIS Open Forum Teleconference discussion, it was decided that a warning should be given rather than an error. Furthermore, the absence of clamp tables would not be reported. The wording I propose is lengthy, but it meets the need for an understandable description of the problem and a remedy. The warning given to the user should be dependant upon the Model_type of the buffer: Input, Input_ECL, Terminator, Series, Series_switch: No warning given. Output, Output_ECL, I/O, I/O_ECL, 3-state, and 3-state_ECL; [Pullup] table missing: "WARNING - Model 'XXX' does not contain a description of the buffer's DC drive characteristics for the buffer's high state (no [Pullup] table). The model is not declared to be an open drain buffer. Perhaps it should be. Alternatively, a [Pullup] table containing all zero currents could be added." Output, Output_ECL, I/O, I/O_ECL, 3-state, and 3-state_ECL; [Pulldown] table missing: "WARNING - Model 'XXX' does not contain a description of the buffer's DC drive characteristics for the buffer's low state (no [Pulldown] table). The model is not declared to be an open source buffer. Perhaps it should be. Alternatively, a [Pulldown] table containing all zero currents could be added." Output, Output_ECL, I/O, I/O_ECL, 3-state, and 3-state_ECL; Both [Pullup] and [Pulldown] tables missing: "WARNING - Model 'XXX' does not contain a description of the buffer's DC drive characteristics for the buffer's high and low state (no [Pullup] nor [Pulldown] table). Therefore, the model is of little use as an output. If this is not a mistake, consider adding [Pullup] and [Pulldown] tables containing all zero currents." Open_drain, Open_sink, I/O_open_drain, and I/O_open_sink; [Pulldown] table missing: "WARNING - Model 'XXX' does not contain a description of the buffer's DC drive characteristics for the buffer's low state (no [Pulldown] table). Therefore, the model is of little use as an output. If this is not a mistake, consider adding a [Pulldown] table containing all zero currents." Open_source and I/O_open_source; [Pullup] table missing: "WARNING - Model 'XXX' does not contain a description of the buffer's DC drive characteristics for the buffer's high state (no [Pullup] table).

PRESS AND WEB PAGE UPDATES Bob Ross reported that Bob Haller authored "The Nuts and Bolts of Signal- Integrity Analysis" in the March 16, 2000 issue of EDN, pp. 61-78, in which IBIS is mentioned in several locations. The article is also available at: http://www.ednmag.com/ednmag/reg/2000/03162000/06ms603.htm Bob reported that in response to the SI reflector discussion regarding general FAQ's on signal integrity, a High Speed Digital Design Topics page now has a "Using IBIS Models" link with general information and other links: http://www.scs.ch/~andrew/hsdd/hsdd.html The Topic Coordinator is Kim Helliwell, and Bob and Abe Riazi are Topic Peers. Comments and assistance in developing this further are welcome. Bob also reported that the participants list has been updated with the Innoveda change from Viewlogic and more information from SiQual, and upcoming events have been updated. The Poster page also has been updated with Innoveda and SiQual logos. Bob also noted that the EIA web site will change, but the existing address will be retained as an alias. NEW MODELS AVAILABLE, LIBRARY UPDATE Bob Ross mentioned that more Motorola IBIS models can be found by searching for IBIS. This probably works for several other semiconductor vendors as well. OPENS FOR NEW ISSUES None. INTERNATIONAL/EXTERNAL PROGRESS - IEC 62014-1 (IBIS Version 3.2) - Cecilia Fleming reported no further information regarding the progress of this document. IEC approved the document in December 1999, and it is awaiting publication. - pr EIAJ ED-5302 Standard for I/O Interface Model for Integrated Circuits (IMIC) - Bob Ross reported that Dr. Hideki Fukuda has been elected Leader, Takeshi Watenabe from NEC, Vice Leader. The group has been following the IBIS futures developments and is interested in the nodal approaches based on the fact that the Silicon Vendors have Spice models. The group wants to continue to work with the IBIS Open Forum. Bob forwarded a letter to the IBIS Futures committee. - IEC PWI 93-1 Models of Integrated Circuits for EMI Behavioral Simulation (formerly designated as IEC 93/67/NP IBIS and EMC Simulation) - Jean-Claude Perrin reported that he plans to revise the document by the end of May 2000 and then make it available to the IBIS committee. It will contain an IBIS style syntax. Bob Ross noted that this was discussed at the European IBIS Summit, and the presentation contains some information about the approach. - JEDEC JC-16 - Bob Ross reported that JEDEC, IBIS, Silicon Tech and Intel are co-sponsoring a free class on IBIS on Wednesday, April 26, 2000, 8 AM to noon at the Silicon Valley Convention Center. The signup deadline has passed. Bob received an estimate of 180 attendees based on 157 signups at the deadline. Ron Werner asked, and Bob noted that class material will be uploaded and be made available. Arpad Muranyi will be the instructor. DATE2000 IBIS SUMMIT FEEDBACK Bob Ross commented that he had good feedback regarding the informative content of the European IBIS Summit Meeting held on March 31, 2000 in Paris, France. DATE 2001 is scheduled in Munich, Germany, March 12-16, 2001. We will probably plan another European IBIS Summit Meeting at that time. DAC2000 IBIS SUMMIT MEETING Bob Ross reported that DAC 2000 is being held at the Los Angeles Convention Center. The trade show portion is held Monday through Wednesday, June 5-7, 2000. The IBIS Summit Meeting is planned Thursday, June 8, 2000 from the morning through early afternoon. The main topics will be our annual election of officers and the connector Specification. Other topics will be related to on going IBIS futures activities. A room has been reserved at the Hyatt Regency Hotel, about six blocks away from the Convention Center and near several other hotels serving the conference. A room further away had been reserved, but that reservation will be cancelled. Guy de Burgh will be handling the signups. The first notice is expected to be sent out next week. Michael Cohen asked if the agenda had been set. Bob noted that we will be asking for presentations, and the agenda will be formed later based on presentations that are contributed. ACCURACY HANDBOOK Greg Edlund reported that as a result of recent SI list interest, he updated the former IBIS Accuracy Specification and sent it to people on the Accuracy committee. It is now renamed I/O Buffer Accuracy Handbook. It contains SPICE model and IBIS datasheet checklists. Greg expects to release the document next week in .pdf format after responding to some review comments. Greg also noted that his company is building an accuracy test board. He is also working on an accuracy trailer and also on an accuracy report that discusses laboratory versus Spice and laboratory versus behavioral simulation. He is awaiting internal approval regarding publishing the data. Greg expects the board and report within several months. COOKBOOK STATUS Stephen Peters had no report. IBIS MODEL REVIEW COMMITTEE DISCUSSION Matthew Flora reported that models from Texas Instruments and Motorola have been sent out for review. BIRD62.6 ENHANCED CHARACTERIZATION OF RECEIVER THRESHOLDS Bob Ross introduced BIRD62.6 by noting that this has been discussed at recent meetings. At the last meeting we made some changes, thus delaying a planned vote to allow for the two-week review period. Stephen Peters and Bob noted some of the changes. The last change was to convert Input_edge_rate subparameters (specified as slew rates) to time subparameters Tslew_ac and Tdiffslew_ac since they related to times crossing the Vin*_ac and Vdiff_ac thresholds. Bob called for a vote. BIRD62.6 was approved 10 Yes, 0 No, and 1 Abstention. BIRD66 - [Model Spec] Vref ADDITION Bob Ross reintroduced BIRD66 by noting that it opens the door to consider related extensions. BIRD66 adds timing test load Vref min and max values. We probably will not add the Rser extension to the timing test load even though it is in some JEDEC documents because JEDEC is moving toward the IBIS timing test load specification. We do need to consider whether to add independent loads for rising and falling waveforms, as done in some PCI specifications. Finally, we could also add min and max values for Rref and Cref. Weston Beal noted that some buffers have different Cref values for min and max conditions. There are two points of view regarding application of timing test loads. It could be used for a common time adjustment value (to calibrate the simulator delays to the specification delays. From this perspective, only one test at typical conditions is needed since the other time is already time correlated. This also relates to how a random part might be measured for compliance to the timing specifications. The other point of view that is being implemented in models is that corner different timing test loads are used for the min and max corners for a wider range of loads. These points of view need to be understood and resolved. Reflector discussion on BIRD66 is needed. IBIS VERSION 4.0 During the above discussion Stephen Peters asked which BIRDs are needed for IBIS Version 4.0. Should there be a cutoff list? Bob Ross noted that we should process the open BIRDs. We also need a BIRD for simultaneous switching noise and perhaps a few other BIRDs. Bob will work on the simultaneous switching noise proposal per Dr. Unger's January 31, 2000 IBIS Summit meeting presentation. BUG34 - No Error Reported for Missing V/I Tables in Output Buffers Bob Ross sent out to the IBIS reflector BUG34 for review and discussion. He had planned to issue other BUG reports, but still has not yet generated them. For background, BUG34 had been introduced in January 1999 and updated in October 1999. It has been classified as an "Annoying" bug and discussion on it had been deferred while we worked on other issues including IBIS Version 3.2 ratification. Matthew Flora, who authored BUG34, stated that he encountered the problem while checking actual models. The IBIS parser gave no error or warning messages for a non-functioning output model that did not have any [Pulldown] or [Pullup] tables. Matthew's revised BUG34 proposed a number of Warning versus Error messages since there were cases where [Rising Waveform] tables and [Falling Waveform] tables or [Submodel] data introduced the correct responses, even for an incorrect model type designation. Bob read one Warning message for a missing [Pullup] table for an output buffer. After some discussion, the group generally supported the longer, more user friendly messages. Matthew noted that such a message would not occur very often. Bob did feel that the "Perhaps it should be." statement was excessive and the wording could be tightened up slightly. Also, Bob commented that the Warning for missing both the [Pullup] table and [Pulldown] table was probably not necessary since individual messages regarding each of the tables could be issued. That should give adequate warning that there is an inconsistency. Bob will work with Matthew off-line to discuss details of the message. Then Matthew plans to issue an updated BUG34. CONNECTOR PROPOSAL REVIEW (CONTINUED) Bob Ross noted that another review meeting occurred on Tuesday, April 11, 2000 with Gus Panella, Bob and Guy de Burgh. Matthew Flora stated that Version 0.941 for the document has been uploaded in http://www.eda.org/pub/ibis/connector/ with most of the changes mentioned in the March 17, 2000 IBIS teleconference meeting. Most of the discussion concerned the required and optional parameters of [Begin_Cn_Model] for the three cases previously defined: Physical connectors using a Defined Physical Pin Physical connectors using Swath Matrix ([Begin_Cn_Swath]) Auto generated connectors using the Swath Matrix and [Begin_Cn_Auto_Map]. Currently, [Begin_Cn_Model] requires the names ModelPinMap and ModelPhyMap. However, there are cases where one or the other is not used. Bob mentioned that "NA" could per permitted for cases where [Begin_Cn_Pin_Map] or [Begin_Cn_Phy_Map] do not need to be defined. Most of the discussion concerned the Swath matrix details. Unlike the package model syntax in IBIS Version 3.2 (and Version 2.1) which document the matrix structures using actual alphanumeric pin numbers, connector model matrices are described indirectly using indices starting sequentially with "1". The Swath matrix format supports specifying extra rows and columns which would be terminated during simulation by the [Cn_Z] resistance value. For example, 2 additional columns could be specified on each end of a 2 by 5 connector. The matrices would have 18 entries (10 for the connector pins, and 4 at each end for the extra connections terminated by [Cn_Z] value. Later, Bob noted that pin cross-over (e.g., side A pin 1 connecting to side B pin 2, and visa versa) had been mentioned, but the existing syntax did not appear to support this. An addition might be made for this. The next meeting is planned on Wednesday, April 19, 2000. The focus will be the input syntax for number of pins, rows, and columns and also the [Begin_Cn_Auto_Map] mode. The intent is to assure that there is syntax consistency for all situations and that the ability to enter conflicting information is minimized. IBIS FUTURES (IBIS-X, API, BIRDxx) Stephen Peters reported on an all day meeting held in Oregon on Thursday, March 30, 2000 with eight people on IBIS Future directions. Arpad Muranyi sent out minutes to the group. Stephen listed a few of the conclusions: Transistor level behavioral support is needed. The ability for simulator vendors to encrypt models was discussed as a needed option A new specification is required. The meeting covered in a number of topics including Review of Arpad's IBIS futures question SI-list reflector responses Arpad's need for die to pad interconnection. (Bob Ross noted that IMIC also does this already in nodal syntax.) Stephen's IBIS-X requirements Scott McMorrow's proposal for a general way to connect pin internal models. Al Davis' proposed macro language. This generated great interest. The next set of actions is to work on the macro language and syntax for nodal connections and netlist connections. The description language would also included signal integrity specification and information parameters. The AR's for the group were: Al Davis make some refinements per the discussion Al Davis write a proposal for a wrapper syntax around the model Arpad Muranyi write a proposed syntax for the header section Since the meeting covered much more than noted above, Bob suggested that Stephen send the minutes to the IBIS reflector. Michael Cohen mentioned that D.C. [Sessions] brought up the idea of using VHDL_A or Verilog_A as the future of IBIS since simulators already process these or have access. This would yield more rapid adoption versus defining a new language. Bob indicated that XML formats for Web based syntax had also been proposed. He and Weston Beal referenced a link with a new XML based Timing Diagram Markup Language (TDML) at: http://www.si2.org/ecix/tdml/ So we might be motivated to consider using a similar XML format. Bob opened the discussion regarding encryption. Stephen noted that he sees technologies that would require hiding the internal intellectual property structures regardless of format. The committee just introduced the idea. Initially, Stephen thought that EDA vendors will do the de-encryption. Raj Raghuram commented that this defeats the purpose of IBIS. Michael added that he has had bad experience with encrypted models. Stephen had planned for another meeting, but its details are still open. BIRD61.1 - ENHANCED CHARACTERIZATION OF RECEIVERS Stephen noted that we will probably reject BIRD61.1 since the behavioral receiver modeling approach seems more promising. BIRD64.1 - PACKAGE MODE SELECTOR Not Discussed. BIRD65 - C_comp REFINEMENTS Not Discussed. NEW TECHNOLOGIES Not discussed. NEXT MEETING: The next teleconference meeting will be on Friday, May 5, 2000 from 8:00 AM to 10:00 AM. ============================================================================== NOTES IBIS CHAIR: Bob Ross (503) 685-0732, Fax (503) 685-4897 bob_ross@mentor.com Modeling Engineer, Mentor Graphics 8005 S.W.
