I'm still working on a release tape of the benchmark circuits used in the appendix to my dissertation. The problem is that it takes a LONG time to track down the origin of 150+ circuits and make sure that they are all redistributable, and contact the originators of those that aren't clearly marked to ascertain whether they are redistributable. Many of these circuits came to Berkeley in bug reports, and thus their origins are buried in my archive of 2000+ old SPICE3 messages. When I can get through all of these, or at least most of them, Berkeley plans to release a tape of collected benchmark circuits. I hope to get this done before long, and will post a message here when such a tape is available. I no longer have any direct input on the matter of ftp access or just mag tape by mail, that decision is up to U.C. Berkeley. Tom Quarles tquarles@mntgfx.mentor.com
