Excuse me, but how did the language on pg. 18 of this presentation:
http://www.vhdl.org/pub/ibis/macromodel_wip/archive/20080401/toddwesterh
off/IBIS-AMI%20Correlation%20and%20BIRD%20Update/IBIS_ATM_BIRD_Update_04
0108.pdf
change from:

| If the Reserved Parameter, Use_Init_Output, is set to "False", EDA
tools will
| use the original (unfiltered) impulse response of the channel.
| The algorithmic model is expected to modify the waveform in place.

into what is in the text of the BIRD107:

| If Use_Init_Output is set to "False", the EDA platform will present
the 
| input waveform directly to the AMI_Getwave call (i.e. without
convolving 
| the waveform with the impulse response returned by AMI_Init).

The two paragraphs have a significant difference and I didn't see
any discussion on that change...  Could someone please explain that
to me?  What happened with the "impulse response of the channel"?

Thanks,

Arpad
