I am getting more consulting gigs, and now I may need to buy Orcad Pspice
I cannot use free suites like LTSpice, since they don?t work with customer EDA.
On option is to use the free PSpice for TI, but that can only handle TI libraries
So I am looking for lowest price Orcad PSpice, even an older used version. The new version comes at about 3000 USD, but for my limited yearly usage I am hesitant to go all in with the newest tool at that price
I was complaining about something LTspice related once and someone here off ered a free copy of his spice which he said was just as good if not better. It might be a bit more mainstream and suit your needs. I think it was Su perspice perhaps? I believe he was not going to continue development and s o was letting people use it for free.
I don't know what is wrong with LTspice exactly as all the spice variants s eems to be mutually incompatible to some extent. If the TI spice is compat ible, Superspice might be as compatible.
What exactly is not compatible with LTspice? My understanding is they acce pt many different format options.

Superspice was developed and sold by Kevin Aylward. I bought a copy from hi m for my own use, and another for use where I worked at the time - Haffmans BV in Venlo in the Netherlands. It worked fine. I stopped using it when LT Spice came along - once we could post LTSpice .asc files here they became a superior replacement for ASCII art.

If you want perfect compatibility with some commercial electronic design ap plication, the people who supplied the commercial application aren't going to admit that LTSpice is close enough.

But nobody is going to promise that it is going to stay compatible forever, unless you give them money to make sure that it happens.
It can be an indirect screening tool for what level you're at; if you don't have it they don't hire you because what they're looking for is the consultant who drops 3 grand on software and never miss it, not "getting more consultant gigs what do I do" and frets about the price-guy.
Yep. LTSpice has encrypted models also, and all the major vendors have verbiage in their software licensing agreement about what they claim you may and may not do with their encrypted models (some of it of dubious legal validity but who can afford the best lawyers I wonder)
You could use your excellent credit to take out a small business loan with a very favorable rate, write it off your taxes as a business expense immediately and then pay off over time and if you make $1 more from it than $3000 + interest - write off savings, adjusted for inflation over the loan term, you can define that as a win I guess.
It's a bit of a gamble but it's $3000 not $30,000. Sometimes it cost money to make money, sucks...
LTspice can't read PSPICE encrypted models. TI is being annoying, shipping those.
BTW: Has anybody had any luck with the new TI PSPICE models? The TINA ones are mostly useless, e.g. the OPA140 model that won't converge unless the supplies are *exactly* symmetrical, and often not even then.
Hardly anybody gets the supply pins right. Some opamps, connected to just a capacitor and ground, generate watts of power at kilovolts from their dumb internal current sources. Would that they would do that in real life.
Sometimes I use the power pins, for boosting and such. Can't trust the models.
I haven't tested many models for PSRR. I doubt many people do that right.

The best designs are necessarily accidental.
Taking out a line of credit is a common method of amortizing at lower interest. Unfortunately software isn't considered as a capital cost, for depreciation, and can't be resold, so you have to write it off in the first year.
