re IBIS rev 2.1 additons to rev1.2

Eitan:

You can convert this model to Version 1.1 IBIS by removing
the waveform tables as you suggest.

Also, you need to comment out or remove the [Temperature Range]
keyword and change the [IBIS Ver] to 1.1. Any of the ibichk
utilities including ibischk2 will validate Version 1.1 models
against the Version 1.1 syntax. With this process, you can
detect other Version 2.1 keywords and subparameters that
need to be removed for Version 1.1 level parsing.

Subject: IBIS rev 2.1 additions to rev 1.2

Hi,

I have generated simple rev2.1 models for CMOS device, that includes
the following elements:
        pullup
        pulldown
        ramp
        rising waveform
        falling waveform
        POWER clamp
        GND clamp

I have a client who cannot use this, since he has only rev1.1
simulator, and asks for a rev1.1 model.

The Parsers in the web-site, as well an editor I have (from Hyperlynx)
verify rev2.1 compatability only (no rev1.1 compatability check...)

What should be removed/changed from the model in order to
make it readable by a rev1.1 simulator ?

>From what I have read, only the rising and falling waveforms should be
removed. Am I correct ? Can someone with a rev1.1 simulator try this
out for me ?

Thanks,
