Thanks, Ambrish! This was the format I originally tried but couldn't get to work. Knowing this was the correct format allowed me to find the actual problem, which was that I had the waveform_start_time value set to a time that was longer than the number of bits in the input file . I'm up and running now, with excellent correlation between the two toolkits so far. Todd.

We will include an example with the bit sequence being entered through an external file instead of generating it randomly in the next release of our toolkit. Please let me know if you have any questions. Thanks, Ambrish. _____ From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Todd Westerhoff Sent: Friday, February 29, 2008 7:34 PM To: ibis-ami-toolkit@xxxxxxxxxxxxx; ibis-macro@xxxxxxxxxxxxx Subject: [ibis-macro] Cadence IBIS-AMI toolkit, bits_file input Hi all, Does anyone have an example of how to specify an input bit sequence for the public Cadence IBIS-AMI toolkit? I was doing some follow-on correlation work for the material I presented at the IBIS Summit, and realized I wanted to control the bit sequence for the simulation. The documentation for the toolkit mentions this input file, but I couldn't find any info on input file format or examples. Thanks, Todd.
