-----------------------MINUTES ---------------------------
Mike LaBonte conducted the meeting.
Call for patent disclosure:
- No one declared a patent.
AR Review:
- Bob look into test load measurement points BIRD
- Text indicates this was intended to be simulation based only.
- Adding measurement based language may complicate things.
- Done.
- Anders create example IBIS file with golden waveforms
- TBD, maybe week after next
- Mike add explanation of OPTIONAL and make 5.2.9 OPTIONAL
- First part not done.
- Mike check IBISCHK code for Pulse_time checks
- Done.
- IBISCHK checks:
Pulse_high, Pulse_low and Pulse_time must all be present or absent
Pulse_time must be > 0
- Mike check IBISCHK code for 5.2.10 and 5.2.11
- Done.
- IBISCHK checks:
[Model Spec] Pulse_low < [Model Spec] Vinl+
[Model Spec] Pulse_low < [Model Spec] Vinh
[Model Spec] Pulse_low < [Model] Vinh
[Model Spec] Pulse_high > [Model Spec] Vinh-
[Model Spec] Pulse_high > [Model Spec] Vinl
[Model Spec] Pulse_high > [Model] Vinl
- Mike mark 5.2.10 and 5.2.11 for deletion
- Done
New items:
- Bob: There will be a quality-related paper by Lynne Green at the summit
- David: Are we ready to present correlation to the IBIS Open Forum?
- Mike and Bob felt the group is not ready.
- Continued review of the IQ Specification:
5.2.12. {LEVEL 3} [Model Spec] Pulse_time reasonable
- Agreement that this can be deleted.
5.2.9. {LEVEL 2, OPTIONAL} [Model Spec] Pulse subparameters complete
- David: We are running into a problem with our choice to avoid duplication
with IBISCHK.
- Testing for pulse immunity is not often performed.
- If pulse parameters are given in a data sheet, they have to be in IBIS.
- David: Leave it OPTIONAL.
- Bob: may be dangerous to require every possible keyword.
- Not all tools may handle it the same.
- Data sheets tend to give full curves.
- Mike: Do we really want to require this?
- Anders: Once BIRD 109 passes the info may be scarce, because it may
require information not currently provided in data sheets.
- Bob: Absolute Maximum Rating values could be used if functional not known.
- We decided to keep this check.
5.2.13. {LEVEL 2} [Model Spec] S_Overshoot subparameters complete
- Anders: Important thing would be the functional limitation
- Not destruction (absolute maximum rating)
- BIRD 109 trying to clirfy the difference
- Will be voted next open forum
5.2.14. {LEVEL 2} [Model Spec] S_Overshoot subparameters match data sheet
- David: This could be combined with 5.2.13
5.2.15. {LEVEL 2} [Model Spec] S_Overshoot subparameters track typ/min/max
- David: We should strike the "0.0V" part of this check:
- Bob: Model Spec subparams are based on actual reference to global ground.
- More s_overshoot is allowed if supply voltage increases.
- Bob ECL & PECL would need separate models.
- We decided to keep this.
Next meeting:
17 Jun 2008 11-12 AM EST (8-9 AM PST)
Meeting ended at 01:03 PM Eastern Time.
