-----------------------MINUTES ---------------------------
Mike LaBonte conducted the meeting.

Call for IBIS related patent disclosures:

- None

Call for opens:

- None

ARs:

- Mike update HTML IBISCHK message files and send to Bob and Lance.
  - Done.

- Mike recover percent format specifications in spreadsheet.
  - No new progress, this will be next.

- Mike add comments to CMPNT, DLY, MSPEC sections.
  - No new progress.

- Lance add comments to EBD section.
  - No new progress.

- Bob add comments to CIRCUIT section.
  - No new progress.


Parser development:

- Bob showed a list of checks related to [Merged Pins].
- Bob: We have been calling this BIRD175 but it probably will be BIRD176 now.
  - These are all syntax requirements, producing IBISCHK errors.
  - Checks 1 through 7 can be done on a separate .pkg file.
- Mike: The [Pin Mapping] example could have more pins to show buses.
- Bob: I'll add that later.
  - This contains suggested error message language.
- Mike: We should designate the messages that will have a line number.


IBISCHK Message Comments:

- Mike: 
- Lance: Those should be separate.
- Bob: That check would be later than version 2.1.

- Mike: Many of these are ifdefed out.
- Lance: Could be processed out?
- Mike: gcc -E can do that.
  - We would have to be careful to define everyting used for compile.
- Bob: We need to keep listing these old messages.
- Mike: The script could generate comments for checks that are ifdefed out.

- Mike: There is a code quality issue if so much code is commented out.
  - Version control would have allowed us to delete unused code.
- Bob: Where would the master copies.

IBISCHK DLL checking:

- Bob: 
- Lance: Could a program just call the DLL?
  - It should not be that complicated.

- Mike: If the AMI has GetWave_Exists=True then it would be an error if AMI_GetWave is absent.
- Lance: Checking for existence of function might be all we can do.
- Mike: We could check 32/64 bit.
  - We could check platform too.
- Lance: we could check for dependencies too.
  - Function parameters would be hard to check.
- Mike: We could check for -1 after clock_times.
  - Also see if impulse_matrix has been modified if Init_Returns_Impule=True.
- Lance: Is there public source code for loading these DLLs?
- Mike: No, but it takes just a few lines of code.
  - David Banas' Python tool started this conversation.
  - But it should be very easy to add to IBISCHK.
  - The code is just slightly different across platforms.

- Mike showed the Algrothmic Model section of IBIS 6.0.
- Mike: The checks should be based on requirements in this section.
- Lance: It would be good to check that the function signatures have been implemented correctly.

- Mike showed contents of the Cadence and SiSoft public AMI evaluation kits.
- Lance: Do they include source code?
- We found source code for a Cadence RX model and a SiSoft TX model.

AR: Mike LaBonte create list of possible DLL checks for IBISCHK.

Meeting ended: 11:53
