Meeting opened: 8:00am on April 10th, 1997

Over 30 people attended the Compact Model Council meeting. This was the first Compact Model Council meeting since joining the EIA under the Electronic Information Group (EIG) in the Design Automation Division (DAD). The meeting was held at Motorola University in Phoenix. The host was Andreas Wild from Motorola. Bhaskar Gadepally (Motorola) presented the agenda and Bertrand Cambou, Senior Vice President and Director of Sector Technology, welcomed the attendees.

EIA Presentation

Patti Rusher (EIA) welcomed the CMC to the EIA and presented the major functions of the EIA. She covered how the EIA was organized, what benefits they can provide, and what are the requirements for membership. Patti passed out EIA Annual Reports as well as membership forms for the CMC. The membership, as of April 10th, 1997 is:

IBM Intel Lucent Technologies
Motorola Siemens Texas Instruments

Other companies pursuing membership, but not completed yet were:

Cadence Hewlett Packard Philips

The question was raised if the CMC would be located in the US only, due to the EIA being a US-based association. The answer was that standards produced by the EIA are ANSI acredited, but that EIA also has very good relationships with the major international standards groups as well. The IEC and EIAJ were two examples.

API team review

The need for more membership participation was presented by David Newmark (Motorola). The participants need to be the simulator owners from the respective companies, not the compact model developers. David reviewed the motivations for the API kits and asked for help from all the members to get participation from their simulator owners.

Dan FitzPatrick (Apteq) presented another possible solution to the API kit problem. It is a little more generic than the previous solutions discussed, as it can handle HDL's as well as compact models. The kit can be used on any SPICE2 or SPICE3 based simulator.

The Action items from this section were:

  1. Get more representation on the API team (All).
  2. A seperate meeting for the simulator owners to address our concerns (David, Patti, Britt, Bhaskar). This includes a press release from the EIA on the API kits and an email from the co-chairs and EIA to help facilitate participation.
  3. At that meeting, contact the experts to see how much work is required and find out their interest level (All).
  4. Make decision on next actions (All):

BSIM3v3 team review

Keith Green (TI) began the review by showing the improvements made to BSIM3's homepage. The site contains the differences between BSIM3v3.0 and BSIM3v3.1.

Chune-Sin Yeh (BTA) presented results from 1/f noise modeling. The plots showed good agreement between data and simulation. Chune-Sin also showed some of BTA's experience with the capacitance model.

Peter Klein (Siemens) showed some of the problems Siemens has seen with the BSIM3v3.1 model. The majority of the attendees agreed that similar results have been seen and that these suggestions would be useful to pass on to UC Berkeley. Impact on a circuit was not shown, but Peter noted that a ring oscillator showed a difference in performance because of the model problems. The problems as well as possible means for solution will be passed on to UC Berkeley.

Keith finished the session with a review of current work at Berkeley. Included in these were:

CMC structure and future plans

Britt Brooks (TI) presented several items concerning the Council structure and how the Council would be organized. The EIA has guides for such organization, however, they encourage each group to use the format that best suits their needs. The largest deviation shown was the terms of elected officers. The EIA recommends terms of one year for the officers.

Britt also presented the plans for standardization for BSIM3v3. There were several steps that should be completed by the end of 1997. Discussions of the budget and how much administration fees would take out of the total membership contribution showed that the budget for 1997 is not firm. The administration costs will be determined based upon how much we use the EIA resources. Further, since the actual membership has not been established, the full amount of membership contributions has only been estimated thus far.

Dick Klaassen (Philips) presented ideas for future work for the CMC. He showed more MEXTRAM information for bipolar modeling and updated the Council on the status of Philip's models that have been released to public domain.

Britt presented the future tasks that the Council might consider. The membership numbers will determine how many of the tasks will actually be addressed, as well as membership interest.

Summary and next meeting planning

The summary session began by polling the attendees as to which simulators they had used for BSIM3v3 work. The list showed several simulators support BSIM3v3. The following simulators have been tested and verified to give the same results that SPICE3 yields using the BSIM3v3 model:

HSPICE SPICE3 Motorola SPICE (internal)
TISPICE3 (internal) ACCUSIM2 (replaced ELDO) SPECTRE

It was noted that good agreement between SPICE3 and the other simulators was the case in the majority of the instances. Peter Bendix (LSI Logic) stated that he had seen wide differences from SPICE3 and HSPICE, but had not passed this information on to Avant!. The differences came from parameter bounding differences which could be addressed by the API kit(s) soultions.

The action item list and next meeting information was determined. The next meeting will be a membership only meeting. Here is the action item list:
