Mike LaBonte conducted the meeting.

Call for IBIS related patent disclosures:

- None

Call for opens:

ARs:

- Mike recover percent format specifications in spreadsheet.
  - No new progress.

- Mike add comments to CMerged Pinsin NumbersT, 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 the latest parser contract and described the changes.
- Bob showed information derived from BIRD175.
- Bob: We have to describe this carefully to Atul.
  - BIRD175 creates different rules for power and ground pins.
  - Before this we made no distinction.
  - For signal pins the new rules don't apply.
- Mike: This is checked after everything has has been parsed?
- Bob: Yes. This is what the EDA tool should do.
  - These tables show the expected package model sources.
  - Circuit_Call can not be used with [Pin Mapping].
  - [Merged Pins] requires [Pin Mapping].
  - Therefore Circuit_Call can not be used with [Merged Pins].
  - There are tables for signal pins, power, ground, etc.
- Mike: This might become background for BIRD175.
- Bob: All pins of a [Pin Mapping] bus must be in [Pin Numbers] or [Merged Pins].
  - But if no [Pin Numbers] at all it falls through to RLC.
  - This rule might be debated.
  - A .pkg file might be checked separately from the .ibs file.
  - In that case some but not all checks can be done.
  - In the context of a [Component] [Pin Mapping] might exist.
- Mike: We should define which checks are Errors and Warnings.
- Bob: They are all Errors.

Meeting ended: 12:21
