Using the SPEC versions of SPICE2G6 and EXPRESSO Sun3/470 (top of the line sun3 cpu) 4761s 461s Sun4/490 (top of the line sun4 cpu) 1486s 151s Which is a factor of 3x. Those with a serious interest in such things should examine the results of commerical codes (which are often much faster, and have been tuned for various platforms). The folks at HSPICE, for example, would probably be happy to chat with you about your CAD needs. -- Keith H.
