CALL FOR PATENTS Bob Ross called for any patents or pending patents related to the IBIS 3.2, IBIS 4.2, IBIS 5.0, Touchstone 2.0 or ICM 1.1 specifications. No patents were declared. MEMBERSHIP UPDATE AND TREASURER'S REPORT Bob Ross reported that we finished the year with 30 paid members. We are now working with the smaller amount of $1279 of fiscal year 2009 money to spend. He was told that we can move $5000 of the 2009 parser income into the 2010 account. We will likely pre-pay DesignCon expenses with 2009 funds. We also sold another ibischk5 parser license. This makes 8 parser licenses total. There is a pending tschk2 parser license sale. Bob mentioned that most members should have received their 2010 membership invoice last month. We have received 7 renewals already. REVIEW OF MINUTES AND ARS Bob Ross called for comments regarding the minutes of the December 11, 2009 IBIS Open Forum teleconference. The minutes were approved with no changes. WEB PAGE UPDATES Syed Huq reported that he has some requests pending to make changes to the roster and other pages. Bob Ross asked Syed to clean up the roster page before archiving the 2009 version. Bob also requested a change to the events page to list Cisco as a sponsor of the DesignCon IBIS summit. MAILING LIST ADMINISTRATION Mike LaBonte reported that we are having some issues with the mail server. Emails may not be going out to the members. Mike noted that he receives about 50 administrative emails per day and he has to review them to determine which emails are spam and which are legitimate emails from non- list members. This activity has ceased, so this is an indication of potential problems. Bob Ross noted that two emails he has attempted to send out to the mailing lists have not gone out. Mike also sent a test email to the ibis-info list, and he has not seen it go through. Bob and Mike will ping the system administrators for help. MODEL LIBRARY UPDATE No update. PRESS UPDATE None. MISCELLANY/ANNOUNCEMENTS None. OPENS FOR NEW ISSUES Bob Ross noted that he plans to discuss a new BUG for the ibischk5 parser, BUG111, during the ibischk5 bug status discussion. INTERNATIONAL/EXTERNAL ACTIVITIES - DASC No update. The DASC file and e-mail archive may be found at: http://www.dasc.org/ - P1735 Encryption No update. The IEEE Study Group on Encryption web reflector archives are found at: http://www.eda-stds.org/ip-encrypt/hm/ -Conferences None. TECHAMERICA STATUS Bob Ross reported that he is following up with some business with TechAmerica including getting signatures on parser licenses and keeping track of new memberships for 2010. IEC APPROVAL ACTIVITIES Randy Wolff reported that he needs to contact Stan Krolikoski, the new DASC chairperson. He has been unable to contact Victor Berman, and Michael Mirmak recommended that Randy try contacting Stan. SUMMIT STATUS -DesignCon Summit Planning The meeting is scheduled for Thursday, February 4, 2010. Bob Ross noted that Cisco is an official sponsor of the meeting. Syed Huq reported that room 203 in the main conference center is reserved. The meeting will be in the same area as most other DesignCon meetings. There is a size limit of 65 for the seating arrangement, but more chairs can be brought in if needed. Syed is arranging food, A/V equipment, etc. He asked if we needed a sign pointing to the room. Bob suggested that we create at least one sign. Syed encouraged everyone planning to attend to register with Lance Wang. Bob is expecting about 50 attendees. Walter Katz asked Bob if the larger IBIS group should discuss the direction of IBIS for 2010 that will be reported on by Bob at DesignCon. Bob suggested we discuss this at the end of the meeting. -European Summit Planning No update. The European organizers are still favoring holding the meeting at the SPI conference in May in Hildesheim, Germany. Sponsorship opportunities for all upcoming IBIS summits are available, with sponsors receiving free mentions in the minutes, agenda, and other announcements. Contact the IBIS Board for further details. IBIS QUALITY TASK GROUP Mike LaBonte reported that the group has been discussing correlation and how it relates to the IBIS Accuracy handbook. Moshiul Haque of Micron drafted a new version of the Quality checklist spreadsheet to be used along with the new IBIS Quality Specification 2.0. This is being reviewed. The Quality Task Group checklist and other documentation can be found at: http://www.eda.org/ibis/quality_ver2.0/quality_ver2_0.pdf IBIS MODEL REVIEW TASK GROUP Randy Wolff gave a summary for Lynne Green of activities of the committee in 2009. Ten IBIS models were received. One model used external circuit features. One model was submitted by an EDA company, and so it was not eligible for distribution. Lynne did a review and provided feedback. No Touchstone, package or ICM files were received. Lynne plans to do a presentation at the DesignCon IBIS summit providing more details. ADVANCED TECHNOLOGY MODELING TASK GROUP Arpad Muranyi reported that the group met last Tuesday. They are reviewing the draft BIRD from Walter Katz that will update the AMI portion of the IBIS specification. This will be ongoing for a few weeks. Bob Ross noted that the BIRD is very large, so it requires a lot of review time. Walter added that many experts are required during the review process. Task group material can be found at: http://www.eda-stds.org/ibis/macromodel_wip/ AD HOC TASK GROUPS (INTERCONNECT) Bob Ross reported that he is hosting the meeting while Michael Mirmak is in Taiwan for the next three months. SiSoft is now hosting the LiveMeeting meeting. Walter Katz reported that all of the issues with adding sparse matrix data to the next Touchstone revision are resolved pending a final review. IBM is presenting data about a binary Touchstone file format. The binary format significantly reduces the size of Touchstone files and speeds up the processing of the files. Walter is working with Brad Brim on a way to wrap subcircuits to expose information about the ports used. This work stems from a presentation made by Brad at several IBIS events last year, and it defines a model connection protocol. Task group material can be found at: http://www.eda.org/ibis/adhoc/interconnect/ PROJECT CONCLUSIONS Bob Ross reported that the parser for IBIS 5.0, ibischk5, has been completed. However, we have not officially closed the project. This requires a vote by the IBIS Committee. We also need to vote to close the Touchstone 2.0 parser, tschk2. Bob called for a vote to close the ibischk5 parser project and accept the source code as completed. The vote passed with the following vote tally: AMD: yes Cisco: yes IBM: yes IO Methodology: yes Mentor: yes Micron: yes SiSoft: yes Teraspeed: yes Bob called for a vote to close the tschk2 parser project and accept the source code as completed. The vote passed with the following vote tally: AMD: yes Cisco: yes IBM: yes IO Methodology: yes Mentor: yes Micron: yes SiSoft: yes Teraspeed: yes TOUCHSTONE 2.0 TSIRD PROCESS DIRECTORY Bob Ross setup a directory on eda.org for documenting Touchstone Issue Resolution Documents, TSIRDs. He showed a sample TSIRD. The directory is found at: http://www.eda.org/pub/ibis/tsirds/ NEW ISSUES None. TSCHK2 BUG STATUS PROCESS Randy Wolff asked if there was a need for an email alias to submit BUGs. Bob Ross said to use the ibis-bug@eda.org alias for now, although we may create a separate email alias later. Randy will add links to the information section at the end of the minutes to document the BUG process. The process is documented in the following directory: http://www.eda.org/pub/ibis/tschk_bugs/ IBISCHK5 BUG STATUS Bob Ross reported that BUG109 found that the parser is not accepting a type “String” as a value for Model_Specific parameters. It also applies for List. The BUG was expanded for type Boolean as well. Code changes have already been made and will include the Boolean type for Corner. String and Boolean are now added as valid types for Corner and List. BUG 110 was submitted by Prabhat Ranjan of ST Microelectronics. The parser rejects legally correct syntax for the D_overshoot_ampl_l and D_overshoot_ampl_h parameters. The parser is expecting to see D_overshoot_amp_l and D_overshoot_amp_h (missing the “l”). The BUG was classified as Severe severity, High priority and Open status. BUG111 was submitted by Bob Ross. This BUG was found in reviewing the fix for BUG109. The BUG found that CR/LF could not be used within the parentheses of a parameter description. This is legal in the specification. Walter noted that you can put a CR/LF before and after any field. These should be ignored and treated as spaces by the parser. Walter felt that this was a serious error. He requested that Bob contact the parser developer to determine how difficult this will be to fix. The BUG was classified as Moderate severity, High priority, and Open status. IBISCHK5 PARTIAL BUG FIX RELEASE Bob Ross reported that there are many open BUGs. There was an emergency fix for BUG108, release 5.0.1. Bob thinks that BUG110 warrants an immediate release that will also cover BUG109. Bob would like to fix BUG111 at the same time, but he needs to consult with the developer to find out how much time a BUG111 fix will take. He noted that there is more work to do before starting a larger project to fix other open BUGs. We will pay the parser developer for further BUG fixes. ICMCHK1 BUG STATUS All BUGs have been closed. No new BUGs have been filed. NEW ISSUES Walter Katz requested we talk about future directions of IBIS for 2010. Arpad Muranyi asked specifically about addressing package modeling. Walter noted that he is looking into the model connection protocol instead of EMD to improve package modeling. Walter added that IBIS Interconnect Spice (IBIS-ISS) is also an item to discuss more in 2010. Bob Ross plans to mention that IBIS is focusing in 2010 on a Touchstone 2.1 release, model connection protocol, and binary format in the Interconnect task group, the AMI BIRD and IBIS-ISS in the ATM committee, and Quality issues. Walter added that this is all short term and maintenance work, so he wondered if there should be a longer term vision. Bob will plan on having a discussion topic at DesignCon for this. NEXT MEETING The next IBIS Open Forum teleconference will be held January 29, 2010 from 8:00 to 10:00 AM US Pacific Standard Time. The next Open Forum summit will be held at DesignCon on February 4, 2010. No teleconference will be available. ======================================================================== NOTES IBIS CHAIR: Bob Ross (503) 246-8048, Fax: (503) 239-4400 bob@teraspeed.com Staff Scientist, Teraspeed Consulting Group 10238 SW Lancaster Road Portland, OR 97219 VICE CHAIR: Lance Wang (978) 633-3388 lwang@iometh.com President / CEO, IO Methodology, Inc.
