About 35 people from member companies, suppliers and universities have attended the Compact Models follow-up meeting in Dallas. The meeting was sponsored by TI, Design Automation group, and SEMATECH likes to thank TI, Design Automation group for the excellent arrangements. Handouts from the meeting will be mailed to all the attendees. For non-attendees the handouts will be mailed on request only. The discussions on the standard interfaces and standard models went extremely well. Based on the inputs I have started working on a brief statement of work for SEMATECH internal planning. The following must be accomplished by the group prior to our next scheduled meeting in Mid August under the sponsorship of National Semiconductor Crop. ############ RESPONSE REQUIRED ############ 1) We have two offers from Motorola and IBM for the model interface kits. The group felt the Motorola spec. will cover the Type 1 specification (requires software glue to connect the models to different simulators). The IBM specification is more advanced and it handles connectivity between models and circuit simulators via environmental variables with good support for hierarchy. There are few other companies that can potentially contribute in enhancing and rapid deployment of both specifications. It is anticipated that we can have something in place for Type 1 by 4Q95, and Type 2 will be targeted for early 96 implementation. ACTIONS FROM THE GROUP: If your company is willing to offer the model interface specification or contribute to the IBM- TYPE 2 specification please respond to SEMATECH within the next 30 days. We would like to consolidate the offers no later than July 25th. 2) In the area of standard model testing, SEMATECH likes to work with several companies. Once a particular model is selected as a candidate, we will proceed with testing using standard test cases. We are looking for pool of I/V data at 0.8, 0.5, 0.35, .25 u with good documentation on the test structures etc. Please let us know how your company can help us in providing reference data for model validations. Companies volunteered so far: IBM, National, TI, AMD, Analog Devices 3) The following individuals have agreed to work with Cal Bittner in refining the IBM Type 2 specification. B. Bhattacharyya - AT&T Alan Mantooth - Analogy David Newmark - Motorola Ralph Sokel - Motorola Kevin Walsh -Anacad Mi-chang Chang -TI ACTION: Cal Bittner to work with the sub group and submit revised document for SEMATECH review by 8/10/95. MINUTES OF THE MEETING AND GENERAL ACTION ITEMS FOR STANDARD MODEL STARTING POINT THE FOLLOWING MAY BE CONSIDERED BY THE GROUP: The minimum requirements for acceptance of any model by the working group is under debate. Availability of source code, documentation and willingness/commitment of the supplier to product enhancement will be critical. BSIM3 v.3 - Public Domain MOS Model 9 - Public Domain? ISIM - University of Illinois. Ford Micro - Internal Model Siemens - Internal Model Jesse .8 (AC41) - Public Domain EKV Model - Public Domain Misman - Internal BNR. BSIM2 - Public Domain Model Interface Requirements - Compatibility - Type 1, Type 2, Type 0 (Eq. only) - Device Topologies - Linking (dynamic) - AHDL - Element dependent T - 'Parameterization' of model parms - TNOM Should be a model parameter precedence over option spec - SCALM - Performance - Numerics error handling limiting - End user support errors - simulator vs model - Object code implementation release process - OS, compilers updates - Node collapsing - Model evaluation - NQS, additional nodes - self heating - TFSOI floating body STANDARD MODELS (these companies agreed to work with SEMATECH by providing measured I/V data for correlation of models) TI - Provide data (IV) National - " " " IBM - " " " AMD - " " " ADI - " Verification will be done by each company. These companies will provide data (subject to NDA requirements) for test groups. ORGANIZATIONAL REQUIREMENTS for model submission: 1. Process for submission of the model.
