Isn't X-Spice the source for Protel's spice simulator in P99SE? If so, I'd suggest a specific search for the X-Spice reference manual. If you can fuind X-Spice references, they are probably the most accurate and complete representations of what Protel uses...Once upon a time, I downloaded it from somewhere, but it was quite a while ago...let's see...
Try this while you can http://users.ece.gatech.edu/~mrichard/Xspice/ FWIW, This Cadence manual may or may not be of value (type into browser as shown) ece-www.colorado.edu/~ecen4228/cadence/files/cspiceref.pdf Or this British resource www.eng.abdn.ac.uk/~eng186/spice Or this Spice enthusiast's Spice page http://www.sss-mag.com/spice.html Have fun aj >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] On Behalf Of Alfonso Baz >Sent: Wednesday, August 17, 2005 6:56 AM >To: 'Protel EDA Discussion List' >Subject: RE: [PEDA] Protel 99SE Simulation > >Peter > >I suggest you do a search for SPICE.
