|Thanks. Till this is a paying job for me, I'm afraid I'm stuck with
|whatever I can get for free or close to free... I just recently ran into my
|first case where I had too many nodes for the eval version, trying to do
|some of the loop-breaking analysis that was discussed in this forum a few
|weeks ago. Worked around it okay, though.
|Say, do you pros typically write the PSpice input by hand, or use the
|schematic capture tool to do it? I keep finding things that I can't do in
|the schematic capture (like setting per-component temperatures, the topic of
|this thread), but it seems cumbersome and error-prone to do it manually;
|seems like I'd always be introducing circuit errors. Or do you use some
|sort of hybrid approach, like sketching the circuit in schematic capture and
|then tweaking it in the text editor?

|Merry Christmas, and if you ever get up to Seattle look me up and I'll
|introduce you to my wine cellar!
Number 2 daughter was just in Seattle for a convention of
water-processing plant managers.
I use PSpice Schematics, although years ago I drew schematics by hand,
node-numbered everything, and then hand-netlisted the thing ;-)
To do temperatures on an individual basis you just need to modify the
part in the symbol library to accommodate entry of local temperature
as a parameter.
I've also occasionally had my oldest son write specialty automatic
editor programs to change the netlist to my liking... like more than
two parameter types in one run.
