About 3-4 weeks ago (16 comp.lsi articles ago at our site) I posted 
three SPICE benchmark input files, complete with their semiconductor
model specifications.  The article was:
	... Message-ID: <1057@mips.UUCP>
	... Subject: SPICE / floating-point benchmarks
	... Keywords: Three new input files
The three benchmarks used different semiconductor technologies: one
was Schottky (bipolar) TTL, one was high-performance digital CMOS, and
one was precision analog CMOS.  I imagine that one of these 3 will
be useful to you in your benchmarking.

If some Usenet site(s) didn't receive this article, I'll be glad to repost.

I'd like to request that you run these 3 benchmarks as well; I've posted
the measured speeds of these, using both Berkeley SPICE 2G6 and
Meta-Software HSPICE, for a few machines {and I'm hoping to lengthen
the list!}.  The original article was also cross-posted to comp.arch
since it dealt with computer performance evaluation.

Meanwhile, here are the model parameters for the 3-micron analog CMOS
technology.  It is optimized for use in building opamps, DACs, filters,
etc., such as you'd find in modem chips, telecomm chips, filters, etc.
