It will also run on Windows 3.1 and WFW 3.11. There is some extra software needed to run on the Windows 3.1 platform. It will run with windows 3.1 it does however require that the Win32s extensions from Microsoft be loaded into windows. I will probably make these available on our web site in the next few days. If you want to get them immediately you could download them from our FTP site at: ftp.hyperlynx.com and then look in the following sub directory: pub/hyperlynx/outgoing. You will need to download 3 very large files: w32s130a.zip, w32s130b.zip and w32s130c.zip Each of these files is approximately 1 megabyte. Each file should be unzipped and the contents copied to a separate floppy diskette. When you have all 3 floppy disks you can install them into your windows 3.1 platform. These are Microsoft programs which we have not modified in any way. These extensions allow Windows 3.1 to run 32bit software just like Windows 95 or Windows NT. I am not sure if the Win32s software will work properly with the Japanese versions of Windows. I don't know of any reason there would be a problem. I don't believe there is any international versions of the Win32s program. I wish you the best of luck. Have a great day...Kellee Crisafulli, HyperLynx Inc.

NOTE: "AR" = Action Required. -------------------------------- MINUTES ------------------------------------- INTRODUCTIONS Hank Herrmann of AMP, Inc. indicated his interest in IBIS as a result of of meeting Stephen Peters at a JEDEC JC-15 meeting. Don Cottrell of CFI joined us to discuss the DCL and Roadmap relationship with IBIS. EIA MEMBERSHIP AND TREASURER'S REPORT No change in the treasury was reported. TI did purchase the ibischk2 source code. MINUTES REPORT, MISC. The October 27, 1995 Minutes have been changed to include Kellee Crisafulli as an attendee. MISCELLANY/ANNOUNCEMENTS None. PRESS UPDATES Patti Rusher reported that the press release announcing the ratification of IBIS as EIA-656 was sent out last week. Will Hobbs indicated that he has already had discussion from a United Kingdom publication editor. Will Hobbs also reported the EE Times article of November 27, 1995 "Group eyes 'free' VHDL sim models", by Richard Goering, mentioned IBIS and quotes by Will in the article. The article discussed the Free Model Forum activity which is seeking to acquire, develop and distribute IBIS models as well. C. Kumar indicated that representatives were visiting Cadence to seek funding from Vendors for modeling efforts. NEW MODELS The PentiumPro (P6 Models) were made publically available November 1. OPENS FOR NEW ISSUES Free Model Foundation Depletion Capacitance Discussion EIA-656 ANSI RATIFICATION Patti Rusher has been pushing EIA-656 ratification as an ANSI standard. She still expects a 1995 date on the ANSI Standard. No further action is needed by the IBIS committee. EIA/IBIS 1996 MEMBERSHIP Patti Rusher will send out EIA/IBIS 1996 membership renewal forms in December. Annual membership is $500 per company. Bob Ross indicated that for the purposes of meeting quorums existing memberships will be carried through the end of January to give time for the membership fees to be paid. No additional golden parser fee is needed for those who have already purchased the source code of Version 2.1, and the same 50% discounts apply for those who have not purchased the source code. Will Hobbs indicated that there are 22 parser licencees. WEB UPDATE (AND EIA) Patti Rusher reported that the Web page issue is still under discussion and is of concern to many groups. Uniformity of content and security are issues, and EIA has hired a consultant to help out. She is pushing hard for a resolution at the Monday, December 4 internal meeting. Syed Huq needs to know what can be published. Everything is in place to be copied. Jon Powell indicated he received copies of logo permission letters from 10 companies. This needs to be checked since Quad Design was not included. Jon will work with Syed Huq to provide the Logos in a common format (probably GIF) so that a collage of logos can be created by pointers. We also discussed the possibility of linking the logos to their respective companies' home pages. Unless the EIA web issues are resolved, further discussion on web plans including the possibility of setting up one separately on vhdl.org will occur at the next meeting. USERS' GROUP Bob Ross reported that the IBIS USERS' GROUP reflector ibis-users@vhdl.org is active. No real activity has occurred to date, but discussion issues are expected. Over 240 members are in this and the ibis@vhdl.org groups. No membership breakdown is available. Many countries are represented. Also there is a new "wip" directory for work in progress under /pub/ibis on vhdl.org to be used for temporarily storing working documents. Currently a draft of Version 3.0 exists which includes approved BIRD28.3 and BIRD30.2. FACE TO FACE MEETING Syed Huq has made arrangements for National to host the meeting on Monday, January 29 before SuperCon96. He has scheduled a room, equipment and food. He is planning for about 35-40. This meeting will be focused on technical discussions. A group dinner is planned to celebrate the standardization of IBIS. AR - Syed Huq post details on meeting and request an RSVP for planning purposes. [Done] Will Hobbs discussed devoting a portion of time to the modeling validation concerns that exist in semiconductor companies, particularly in relations to on-going production testing. The problem is how to verify in the testers that the components meet the predictions of the models - what to measure, how many points on a V/I curve are sufficient, etc. Can and/or should IC vendors guarantee by test that the models accurately bracket the silicon characteristics? Intel and National will participate in this, but other vendors are encouraged to give their experiences and concerns as well. Another important segment is to seek actual users of IBIS models and ask them to present their experiences and problems. IBIS participants who are users or who have worked with users are encouraged to seek their participation. Several members indicated that they will follow through on this. Syed Huq did a direct polling of roster members and found that 7 supported IBIS Version 2.1 and 7 supported Version 1.1. His concern was that some Version 2.1 level models will not work properly at lower levels and encouraged EDA Vendor Discussion of their IBIS Verison 2.1 plans. Such a discussion can also be tied in with the general modeling issue discussion. People who have topics to present should summit them to Bob Ross, Syed Huq or Will Hobbs. Bob, Syed and Will will coordinate the agenda. AR - Everyone solicit participation by IBIS Users. AR - Anyone who wants to present notify Bob, Syed or Will. MODEL USAGE TRACKING Will Hobbs mentioned Intel has IBIS models on their bulletin board, but is not aware of any usage tracking activities. Syed Huq stated that National IBIS models are available from the external National Web site: //www.nationalsemi.com They are trying to find a way to track models usage. GOLDEN PARSER UPDATE Jon Powell created the executables for ibischk2, and Bob Ross put them on vhdl.org. Will Hobbs has sent out the final version of source code. Several problems have been discovered by Bob Ross and Chris Rokusek which will require a revised bug-fix release. Our intent is to capture all of the bugs and do an update in January. These problems will be sent to Paul Munsey for review and a quote on fixing the problems. AR - Anyone finding Parser bugs submit them to Bob Ross. Include a test case, if possible. So far the bugs are (1) not accepting multiple [Disclaimer] keywords, (2) giving an incorrect Warning message when metric unit multipliers are used for [Define Package Model] matrix entries, and (3) not detecting a syntax error for incorrect [Model] sub-parameters "Model_type=", "Polarity=", and "Enable=". SPICE TO IBIS VERSION 2.1 Bob Ross reported that he has submitted some bugs and enhancement requests on s2ibis-v2.091 (a Beta version). Since this is a Beta version an update is expected. BIRD31 - Connector Models Bob Ross introduced BIRD31. The primary aspects are that it relies on existing syntax and introduces no new keywords or sub-parameters. It is a new section which will follow the Package Modeling Section in the Specification. The controversial aspect of this proposal is that connectors would be split into two parts for each board. They would be joined by Simulator specification which "mates" the models by series concatenation. Hank Herrman of AMP expressed concern that "mated models" representing connectors are not easily split, nor are they necessarily meaningful in a split mode, which represents unconnected connector. So an alternative proposal will be a "mated connector model" by itself. Dave Moxely suggested that Components which are for connector pins could be designated by a "mated model" keyword. The BIRD did not address cables, but one possiblility is that cables could be represented by mated models as longer connectors. Hank also would like to see a parameter that specifies the bandwidth or minimum time response for which a connector is valid because models of increased complexity are needed for higher speed applications. Bob Ross will write up some of the discussion and carry this on the reflector and at the Face-to-Face Meeting. BIRD28.3+ PACKAGE MODEL ENHANCEMENT Stephen Peters has reviewed C. Kumar's extension and now sees the merits of adding a pin ordering file and Matrix name parameter for extending the package model. Kumar reported that one benefit will be to call smaller matrices that are used often, for a more compact description. This would allow a more general set of coupling relationships. C. Kumar plans to submit to Will Hobbs a new BIRD on this. Another discussion included generalizing the loss model to include the G matrix, since it may become more factor in MCMs, package models, cables with dielectric losses. This would take another BIRD. EGG8 - PHYSICAL PACKAGE DISCUSSION Bob Ross introduced the subject of EGG8 which would be a significant departure for just the IBIS I/O models scope. Will Hobbs expressed the concern that one of the biggest modeling issues is how to describe MCMs and SIMM packages. So this proposal is of great interest to the IBIS community and needs to be pursued. A discussion at the next meeting can be reserved for this issue. DCL RELATIONSHIP WITH IBIS Don Cottrell of CFI reported that Ron Christopher has identified areas where the Delay Calculation Language (DCL) and IBIS may be related. DCL needs loading conditions for correct delays, and IBIS can be of help. DCL focuses on delays within an MCM or Chip. He requested that someone on the IBIS committee be identified to work with him and the DCL community on any joint common ground issues and help generate possible proposals. Stephen Peters voluteered to get involved and report back on progress. EGG6 - TTL and CMOS Chris Rokusek indicated that the efforts to distinguish technologies by the data itself suggested by Arpad Muranyi and others does not always work. His major concern is that to simulate the rising edge of a TTL model, it is voltage source driven, versus a current source driven for CMOS and pulldown characteristics. ECL type structures are already differentiated by Model_type. He will present his findings on the reflector to stimulate discussion an consideration of alternatives. DEPLETION CAPACITANCE Bob Ross indicated that the depletion capacitance issue which has been discussed in the past is ripe for an Egg to generate more discussion. He plans to submit one. NEXT MEETING: It is set on Friday, December 15, 1995, and the following meeting is on Friday, January 12, 1996 after the Christmas and New Years Holidays. ============================================================================== NOTES IBIS CHAIR: Will Hobbs (503) 264-4369, Fax (503) 264-4210 will_hobbs@ccm.jf.intel.com Server Chipset System Validation Manager, Intel Corp. 2111 NE 28th M/S JF1-57, Hillsboro, OR 97124 USA VICE CHAIR: Jon Powell (805) 988-8250, Fax: (805) 988-8259 jonp@qdt.com 1385 Del Norte Rd., Camarillo, CA 93010 SECRETARY: Bob Ross (503) 603-2523, fax (503) 639-3469 bob@icx.com 10220 SW Nimbus Ave, K4, Portland, OR 97223 The following email addresses are used: ibis-request@vhdl.org To join, change, or drop from either the IBIS Open Forum Reflector (ibis@vhdl.org), the IBIS Users' Group Reflector (ibis-users@vhdl.org) or both.

That almost never happens. Also, you have done an excellent job of capturing all the discussions that took place in the last meeting. There are two points that I think were discussed that I did not see in the minutes. Perhaps they were too small to include but I would like to clarify and confirm them. First, I thought someone mentioned the desire to discuss connector modes at the Face-to-Face Meeting in January. I wonder if anyone has any specific points they would like to discuss. Since I am considering trying to attend, this could significantly influence my decision. (Cross country trips for a one day meeting are not popular with me or my management.) Second, when BIRD 31 was discussed, I recognized the need for many users to have unmated models to simulate "not-fully-populated busses". They would not be used for such analyses as cables or I/O connectors when there is a complete interconnection. While we do not routinely supply unmated models now, there is no reason that they could not be provided. They would even be simpler than "part of the mated model" which the BIRD suggests. What I recommend is that two types of connector models be defined. First, mated models for most interconnection applications. Second, unmated models that have no through connection for situations that demand simulations of "not-fully-populated busses". I hope these points are helpful to the forum. I enjoyed participating with you all and look forward to future work together. Regards, Hank Herrmann Technical Staff Member AMP Incorporated, Electro-Magnetic Technology M.S. 106-14 P.O.

My concept of "unmated" is that the model should be self-sufficient (i.e., work properly without extra 'patches and band aids' and have connections at one side only. So it would look like this ... Board1--> conn_model (unmated) There would be no additional load required outside of the model. For SPICE type simulators there may have to be some standard DC path, or 'assumed load' to enable an unmated connector model to function properly. That would not likely be required by most models, however, because there would already be the necessary DC paths to satisfy SPICE within the model itself or the bus. A standard load may be something that should be defined for stand-off type stacking connectors that are long relative to the models' minimum applicable edge rate. At this point I have only proposed, for consideration, the concept of both mated and unmated connector models as opposed to a mated model with an interface connection such as is proposed in BIRD 31. Many details need to be worked out until that is finally accomplished if the concept is acceptable to everyone. Hope this is helpful.

Because of stored charge, a clamping diode will not release instanteously from the clamped mode as predicted by IBIS models. There will be a delay while the diode is turning off. This creates a glitch which itself can propogate up and down a line. This glitch is significant enough that IBIS should support a way to model its effect. The major contributor to the effect is the TT parameter which contributes a non-linear transit time capacitance when a diode is conducting. The proposal here is to use a similar parameter by adding [TTgnd] and [TTpower] keywords to the [Model] keyword description. Bob Ross, Interconnectix, Inc. EGG9 - Proposal for handing Stored Charge Effects: |============================================================================== | Keywords: [TTgnd], [TTpower] | Required: No. | Description: The data for these keywords enters the transist time parameters | to estimate the transit time capacitances for the [Gnd Clamp] | and [Power Clamp] tables. | Usage Rules: For each of these keywords, the three columns hold the transit | values corresponding to the typical, minimum and maximum | [Gnd Clamp] or [Power Clamp] tables, respectively. The | entries for TT(typ), TT(min), and TT(max) must be placed on | a single line and must be separated by at least one white | space or tab or tab character. All three columns are | required under these keywords. However, data is required | only in the typical column. If minimum and/or maximum values | are not available, the reserved word "NA" must be used | indicating the TT(typ) value by default. | Other Notes: The transit time capacitance is added to C_comp. Its value | value Ct is approximated by Ct = TT * (q/kT) * Id where TT | is transit time, q is electron charge, k is Boltzmann's | constant, T temperature in degrees Kelvin, and Id is the | dynamic diode current when the diode is conducting. Id can | can be found from the [Gnd Clamp] or [Power Clamp] operating | points. If the [Temperature] keyword is not defined, use | the default temperature for all Ct calculations | |------------------------------------------------------------------------------ | variable TT(typ) TT(min) TT(max) [TTgnd] 10n 12n 9n [TTpower] 12n NA NA | |============================================================================== Refer to Spice diode reference information concerning the complete equations. The emission coefficient (N) is assumed to be 1. For measured values or cases where N is not 1, use the effective TT values. So the TT values may not be the exact values used in a Spice model. The Spice diode and transistor models differs slightly from the IBIS Clamp models. The definition and position of the capacitances is different. Furthermore, the IBIS table combines the diode and resistor, but can support more complex non-linear characteristics. Intrinsic RS Diode +-----+ |\ | ----> Id | | ----> Id o---/\/\/\--+--| >|--+----o +-----|Clamp|-----+ | |/ | | | | | | | | o----| +-----+ |----o | | | | | | | | +---| |--+ +-------| |-------+ | | | | Cj + Ct C_comp + Ct Fixed values of C_comp serve to estimate voltage dependent non-linear junction capacitance plus other metalization effects The Ct value is a function of absolute temperature. As an approximation, the default typical temperature is sufficient if [Temperature] is not specified. It is recommended to include the [Temperature] keyword when TT is specified to remove ambiguity regarding minimum and maximum transit time calculations for CMOS versus Bipolar technologies. An underlying assumption is that the equations will be applied only to the Clamping data, not the combined data that includes [Pulldown] and [Pullup] data. So when this detail is needed for Output models, the clamping data needs to be derived, if not provided. Because of these differences and possible missing details, the simplified equation and approximation approach is justified to capture the dominant behavioral effects. So the TT values may be the effective values consistent with the IBIS model and data. There are several formatting choices to describe transit time: (1) A [Model] sub-parameter similar to Vinl and Vinh, e.g., TTgnd = 12n TTpower = 10n This was not chosen because minimum and maximum process Spice models may have different values. (2) A [Model] sub-parameter similar to C_comp, e.g., TTgnd 10n 12n 9n TTpower 12n NA NA This was not chosen because the rules for minimum and maximum columns for C_comp are by magnitude, whereas the rules for TT are by process extremes. (3) A [Gnd Clamp] and [Power Clamp] sub-parameter similar to C_comp, e.g [Gnd Clamp] TT 10n 12n 9n This was not chosen for the same reason as (2) and because of [Gnd Clamp] and [Power Clamp] table complexity. (4) A [Model] keyword modifier similar to [Temperature] and other keywords which are a function of typical, minimum and maximum process and measurement conditions. e.g., [TTgnd] 10n 12n 9n [TTpower] 12n NA NA Since these keywords are related to the [Gnd Clamp] and [Power Clamp] tables and to the conditions under which they were derived, this format was chosen.

I have assumed that Rs itself has a negligible effect for the region of operation. However, the topology of the IBIS model is not exactly that of a Spice model, so I would expect some difference. Can you characterize how large the difference is or what the different effects are? Also, my intent was to create a current dependent capacitance model where the current is better defined than the voltage.

However, for the purposes of Time response simulation, the C_comp and/or Ct could go to any reference voltage. The main idea is that both the [Gnd Clamp] and [Power Clamp] diodes may independently contribute to stored charge effects. The discussion that is taking place is showing the importance of understanding the details and assumptions of the Spice and IBIS models. I do not think we are in technical disagreement. I think the value and position of Rs or its effective value within tables can be important for properly handing the stored charge effects and time constants. The real concerns are: is the proposed approach accurate enough?, or what alternative approach would be better - within the IBIS framework?

Therefore, the current of the capacitor should go through the appropriate GND or power pin to make the bounce simulation more accurate.

NOTE: "AR" = Action Required. -------------------------------- MINUTES ------------------------------------- INTRODUCTIONS Jon Powell chaired the meeting. Sri Jandhyadla and Tareq Shahwan joined us from Texas Instruments, Sherman Texas. They have been providing IBIS models directly to customers on a per request basis including models for JTAG devices and bus drivers. Models provided include components in the LVT and ABT series. They are working on GTL models. There is still discussion on how best to distribute IBIS models. EIA MEMBERSHIP AND TREASURER'S REPORT The membership is the same and the treasury has been reduced by a payment for parser code development. We estimate $7,000 to $8,000. MINUTES REPORT, MISC. The December, 1995 Minutes National Semiconductor Web Site has been corrected to read: http://www.natsemi.com Two additional points by Hank Herrmann on the BIRD31 discussion are added to the minutes. (1) Connector models will be discussed at the Face to Face meeting, although specific items of discussion have not been identified. (2) "not-fully-populated busses" could be modeled by separate models rather than by partial models as the BIRD suggests. The minutes will contain the more detailed discussion which Hank has sent to the reflector. MISCELLANY/ANNOUNCEMENTS None. PRESS AND WEB PAGE UPDATES "Meeting Timing and Signal Quality Requirements" in Printed Circuit Design, December 1995 by Rod Strange and Peter Suaris mentions IBIS. The web page discussion documented below occured at this time. NEW MODELS Syed Huq reports that some updated versions of National models have been submitted to Michael Steer. Arpad Murayni reports that information concerning the Intel 82439HX has been sent to Michael Steer concerning IBIS model availability under NDA. OPENS FOR NEW ISSUES Egg9 - Transit Time Modeling. EIA-656 ANSI RATIFICATION Patti Rusher reported that on December 13, 1995, IBIS has been formally ratified by ANSI as ANSI/EIA-656. A motion was made by Bob Ross and seconded by Jon Powell to forward ANSI/EIA-656 to IEC (International Electrotechnical Commission) working group TC-93 on Design Automation as the first step toward international ratification. Motion was approved by unanimous vote. Patti will forward the document at a January meeting. She expects the standardization process may take up to 3 years. EIA/IBIS 1996 MEMBERSHIP Patti Rusher will send out EIA/IBIS 1996 membership renewal forms in early January instead of December. EIA WEB UPDATE Syed Huq has been working with Patti Rusher and Steven Malone on Web page details. They are making excellent progress and will report on the reflector when the Web page is up. All documents are approved. Contents of the Web page include: Intel EDN article Links to vhdl.org for IBIS information including Models IBIS Specifications Roster FAQ's (Frequently Asked Questions) Links to Member Companies Home Pages. Syed needs to know which companies are member companies. Jon Powell has logo information and Logos from 12 companies. Since HP nor NCSU are not official members, their logos cannot be used. TI is planning to submit a logo, (and sign the EIA/IBIS permission letter form set by Patti Rusher), but at this time does not need a link to the company home page. Links can be provided later. Jon Powell reported that the following companies have supplied logos: Interconnectix, ATT-GIS, National Semiconductor Quantic, Contec, Hyperlynx, Incases, Intel, Unicad, Quad Design, and Cadence. FACE TO FACE MEETING Syed Huq has made arrangements for National to host the meeting on Monday, January 29 before SuperCon96. So far he has 15 confirmations. Lunch and snacks will be provided along with the meeting place. For those who are staying over, plan on a celebration dinner together. Syed will send another reminder giving more details on location. TI indicated that they may send one or two people. Syed has made some other semiconductor vendor contacts. While details will be firmed up later, Intel and National are expected to participate on the model development/model validation topic. Other topics with details to be firmed up later are expected to cover connector modeling, stored charge modeling, feedback mechanisms, TTL measurements, adding more timing specifications, hysteresis, bus keeper circuits, etc. At Design SuperCon96 on January 30 - February 2, there will be at least two presentations by National Semiconductor and one by Quad Design which will refer to IBIS. MODEL USAGE TRACKING This issue will be dropped until there is further proposals by vendors. National's Model listing on their Web site links directly to vhdl.org so that only a single library is managed. Jon Powell found a Web site which appeared to register participation. He will forward details to Syed Huq. GOLDEN PARSER UPDATE Several errors have been reported by Chris Rokusek to Bob Ross. One of them will lend itself to a specification clarification BIRD since the ibischk2 is functioning correctly. These problems will be sent to Paul Munsey for an update expected early next year. AR - Anyone finding Parser bugs submit them to Bob Ross. Include a test case, if possible. SPICE TO IBIS VERSION 2.1 Bob Ross reported that a crash bug found by Altera has been sent to NCSU on s2ibis-v2.091 (a Beta version). WINIBIS (NEW DISCUSSION) The Hyperlynx supplied utility was discussed. Bob Ross reported success in using it on Windows 3.1. Dave Moxley and others reported problems bringing it up on Windows NT. It gives a similar error to Windows 3.1 when the latest Win32S is NOT loaded. The action item is to contact Kellee Chrisafulli directly. EGG8 - PHYSICAL PACKAGE DISCUSSION No discussion. BIRD31 - CONNECTOR MODELS Some discussion occured and Bob Ross still plans to submit some examples to the reflector. Bob indicated that the required keyword [Description] for the expanded [Define Package Model] extension could be used to place any edge rate or bandwidth limitation requested by Hank Herrmann. Jon Powell raised the question regarding what EDA vendors are supposed to do with this information. BIRD28.3+ PACKAGE MODEL ENHANCEMENT C. Kumar has sent a proposal to Stephen Peters for early review before sending it out as a BIRD. EGG6 - TTL and CMOS Jon Powell reported that there exist counter-examples for all proposed methods to distinguish the technologies from the data itself. However, even though the transition mechanisms are different, he is thinking that the test load to get the dynamic parameters are a more important factor. So no change in the Specification may be needed. If he discovers some test load set that works well, he will supply the recommendations. EGG9 - HANDLING STORED CHARGE Bob Ross discussed EGG9 and reflector comments. He agrees with Jon Powell that RS is important. Jon indicated that it may not be a factor if RS is less than 4 ohms. This needs to be validated. The issue is that the transit time capacitance is modeled in parallel with the intrinsic diode, to the time constant remains constant. When the IBIS Clamp table is used, the effective RS is also included. This makes the time constant vary with forward diode currents, and may cause different effects. Since the IBIS Clamp table can represent a clamping circuit instead of just one diode or transistor, the notion of an effective TT is put forth. It may be derived indirectly - supply the TT that matches the desired performance, as opposed to trying to use the TT in a Spice model or obtained directly. For background, Bob indicated that other approaches are possible for this problem. (1) A complete simplified verion of the diode equation used by Spice could be added (the set of parameters would be specified to describe this diode) and the Clamp tables would be difference currents from the measured IV characteristics. (2) Or a best fit diode equation could be extracted form the tables to estimate RS and intrinsic diode, although experience indicates that this does not always give a reasonable estimate. This will be a topic for the face to face discussion and is open for more reflector discussion. HYSTERESIS AND INPUT RISE TIME SPECIFICATION (NEW DISCUSSION) Arpad Muranyi discussed IBIS USERS' GROUP reflector questions from John Fitzpatrick. One question dealt with whether IBIS supports hysteresis. Bob Ross indicated that hysteresis could be supported by putting in the smaller threshold for Vinh and the larger one for Vinl. This may work for timing limits. One question is whether the actual threshold values or the specification limits should be used. The data itself may cause a too conservative timing estimate for a hysteresis input designed to tighten up the timing tolerances. So there is expected to be more discussion on this subject at the Face to Face Meeting. Another topic concerned a Tinr and Tinf input rise and fall time specification. This would be similar to the threshold limits Vinh and Vinl that are specification limits for the [Model]. A few devices do have input rise and fall specifications. For some cases, if the input is too slow the device can be destroyed. In other cases, it may be needed to assure compliance with other timing specification. This also can be a topic for the Face to Face Meeting. DOUBLE COUNTING OF PULLUP AND PULLDOWN RESISTORS (NEW DISCUSSION) Arpad Muranyi recounted his experience and caution that one must understand the Clamping tables when modeling devices with internal pullup or pulldown resistors to avoid double counting the resistors. Bob Ross indicated that it is permissible to supply data outside of the (minimum) ranges mandated by the Specification. The minimum ranges are appropriate for most devices where the clamps will converge to nearly 0ma at the Vcc points. With an internal pullup, for example the [Power Clamp] table would be extended all the way to -Vcc to accurate model its effect. Arpad has correctly taken this into account in the models he has supplied and cautions others to be alert to double counting problems if they have internal pullup and pulldown elements. Dick Ulmer indicated that the values may be negligible (e.g., 50k) for many cases. However, there can be cases where the elements are significant.

The good news is ACER has IBIS models for many of their IC's. The bad news is I don't know who to contact at ACER and at least one of their models has a minor bug. ACER fell into the Power_clamp table polarity problem that most new IBIS file creators hit. The signs on all the currents in the table are wrong. HyperLynx tools detect this and correct the problem. Other vendor's products may not correct this problem so it is important to get the word to ACER before they create any more models with the currents backward. Does anyone know who to contact at ACER, or is anyone at ACER reading IBIS mail? I was not able to find out which ACER model was causing the problem. Have a great day...Kellee Crisafulli, HyperLynx Inc.
