Review of previous meeting minutes:

  Without objection the minutes were approved.

ARs:

- Mike LaBonte to complete BIRD appendix for parser contract.
  - Some progress.

New IBISCHK bugs:
- Bob: We had an inquiry about an IBISCHK issue, but no testcase yet.
  - The message is about non-zero ISSO at VDD.
  - This may or may not be a bug.
- Bob: Arpad sent a bug about a year ago, but it hasn't been processed yet.

IBISCHK7 parser development:
- Mike showed the parser contract draft 8.
- Mike: For BIRD 182 we might suggest the messages.
- Bob: If a pin bus_label is not found in [Pin Mapping], it must have a POWER/GND Signal_name in [Pin].
  - With BIRD 189 there is a bus_label keyword.
- Mike: The BIRD 182 change description here looks sufficient.
  - An email detailing this would be helpful.

AR: Bob Ross to send material on required parser changes for [Pin Mapping]

- Mike: BIRD 183 is editorial, but some messages might need to be changed.
- Mike suggested terminology changes for four matrix messages.
- Bob: These changes would apply to all versions, not just 7.0.
- Mike: This might break some regression tests.
- Bob: This could cause line wrap issues.

- Mike: BIRD 184.2 requires new checks.
- Bob: Model_name and Signal_name should be all lowercase.
- Mike: One question is whether to call out all errors or just the first.
- Bob: We do not know which name is in error.
- Mike: This only says they differ.
- Bob: We should stop after the first error.

Mike: BIRD 185.2 ...
_ Mike: This is a list of places in the code that prohibit reserved words.
- Bob: The BIRD is editorial, no checks should be needed.
- Mike: Then I will delete these and recommend no parser changes.

- Bob Ross moved to adjourn. Mike LaBonte seconded.
  - The meeting ended without objection.

Meeting ended: 11:55 ET

Next meeting April 24, 2018
