When I noticed them trying to neuter PSpice I stopped paying the annual maintenance fee and held-up at v15.7 for the simulator and made my own patches to PSpice Schematics.

I recall a couple? years ago you were actively searching for PSpice replacements. I take it you never found anything particularly suitable? It's just dumb on Cadence's part to neuter PSpice... ---Joel

For me I haven't found anything that comes close to working as good as old original MicroSim Schematics... and it's VERY smoothly hierarchical. And PSpice Probe is the "cat's meow" for creating the "pretty pictures" that the customers want to see to prove that a chip's expected performance meets specification. Around SED, though, "specification" seems to be a dirty word :-( ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Spice is like a sports car...

At clients I am actually known to be a bit on the "insisting" side when it comes to specs. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

These days, "close" is good enough for horse shoes, hand grenades, and engineering specs. :-) ---Joel |
