Re: Phase-in of IBIS 2.1 functionality

Hi again IBISgurus:

Along with the items that Will Hobbs has pointed out, I would like to stress
that Differential I/O capability is a MUST along with Multiple-rail support.

The following Keywords are needed:

1) [Diff Pin]
2) [Pullup Reference], [Pulldown Reference], [POWER Clamp Reference]
   [GND Clamp Reference]

I have also got commitment from one of our groups to convert about
30 SPICE models to IBIS. That will depend on S2IBIS availability.

I will join Fri's meeting a bit late due to a conflict with other meetings.
My apologies..
Best Regards,
Syed.
