Call for patent disclosure:
Arpad wondered if this is still necessary
- Michael Mirmak said policies may be changing, but keep doing it
No one declared a patent.

- Question about if this is for just the API or for IBIS SPICE extensions
- Michael M: this might be split up
- Michael M asked Arpad to clarify the AR text
- TBD
AR: Arpad clarify text of "parameter passing syntax" AR
- Arpad: Review the new macro library files.

- TBD
- Ian send relevant papers on related IEEE work
- TBD
- Ambrish show voltage scale on impulse wave in presentation
- Done
- Ambrish send presentation to Mike
- TBD

New Discussion:
Testing progress:
- Ambrish:
- Dealing with bugs in Cadence tester code
- Mike S:
- Good news is that it didn't crash
- Bad good news is that nothing happened
- Problem in GetWave function
- One more experiment to try using Cadence impulse response
- Todd:
- Having these programs available has been very helpful
- So far only binaries have been shared
- Debugging is a little slower
- Ray:
- Kumar will send source to SiSoft
- Should be equally debuggable without source code
- Data would be delivered as text
- Mike S: this needs to be run all together in a debugger
- Ray: Yes, this would be easier
- Todd:
- There probably have been differences in spec interpretation
- Can be multiple testers, but they have to be consistent
- Radek:
- Why is tester code needed?
- Mike S: Tester code is needed to debug the path to the model code
- Could use printf debugging, but that is not the favorite way to debug
- Radek: In Matlab I can debug without the platform source
- If tester had debug capabilities source code would not be needed
Planning for Asia IBIS Summit
- Hemant: We could use our DAC update as a starting point
- Michael M: Those users already know this fairly well
- Not much background detail should be needed
- Hemant: the DAC presentation really was just an overview
- Todd agreed
- Todd will present for us
- Bob:
- Can get up to 1/2 hour
- Cadence might co-present
- Hemant: Todd can present
- Huawei may present on this topic
- Todd will be on vacation the next 2 weeks
- Will try to send a presentation by Friday
- Presentations will be language translated
- Michael M: Do not assume simultaneous translation
- Presentations may have to be shortened
- Bob:
- Arpad penciled in temporarily
AR: Todd send draft Asia summit presentation
Kit status:
- Todd:
- SiSoft kit includes:
- Command line tester exe
- 4 tap model exe
- Basic documentation
- Windows & Linux
- Giving IBIS the option of licensing the source
- Ready to send after a few copyright notices are finished
- Could go out at the end of this week
- Let Todd know
- Hemant:
- Sample Rx model ready by Wednesday
- Source will be open
- Source will go to SiSoft first for debugging
- Tester exe
- Documentation
- Picking a date soon for kit release
- Ambrish: Who decides what should be in the tester kit?
- Todd: Depends on the IBIS committee
- Michael M: IBIS member and partner code access are separate
- Todd: licensing is not SiSoft's decision
- This is like the ibischk program
- Michael M: ibischk is written by contractors
- icmchk was donated free
- Mike S: SiSoft can change it to suit IBIS
- Arpad: paying licensees might be able to embed code
- Todd: Copyright for models allows free use with copyright retention
- Master source archive needs to remain with IBIS
Next meeting: 7 Aug 2007 12:00pm PT
