It's a circuit :simulator. Here are measurements of a Sun3 and a Sun4, both running I may be wrong but..... So far as I know [and I've seen the code] SPICE is not a heavy user of integer multiply/divides. It does use a fair amount of floating point. Therefore, trying to get a measure of integer multiply/divide performance using SPICE is grasping at straws at best. -- Bob Silverman #include Internet: bs@linus.mitre.org; UUCP: {decvax,philabs}!linus!bs Mitre Corporation, Bedford, MA 01730
