PSP files for SPICE subcircuits

Just curious: Avago uses files ending on *.psp which used to be PaintShop files. But it's text files, with some weird characters added in there that SPICE will barf upon.

Anybody know why they did that and maybe an easy trick to boil them down to regular ASCII?

Might be encrypted device models. ...Jim Thompson

Drat. Hurumph.

That would be a sales volume reduction tool. I was able to pry the numbers out of one of the files but now have to verify it all. A lot of people would simply move on.

googling seems to suggest that it could be Penn State Philips models?

Joerg, Can you send me a copy?

Encrypted models are usually 100% gobbledygook. So what you have may simply be some headers and footers inserted by some obscure text editor. ...Jim Thompson

Done. This one was easy but on bigger RF devices that's a pain.

But that's for LDMOS and stuff, not for diodes, and AFAIR requires an expensive special simulator:

For diodes this would be a hefty damper on sales.

Looks like it's only one character type out of place, for whatever reason, some sort of box instead of carriage returns.

So, Avago = good company :-)

Are you opening it in Notepad? Notepad doesn't understand encoding, try Wordpad, or another editor which does.

If you want to write a script, I'm guessing the "box character" is 0x0A, whereas Microsoft uses 0x0D, 0x0A for CR+LF. Simple find and replace will 'fix' it.

Yup, that was the problem.

T'is what I ended up doing. The SPICE files run nicely, it's just coming in a raggedy format. For some reason other mfgs don't do that, their stuff opens correctly in Notepad.

Notepad++ (free) will automatically convert UNIX line endings to DOS/Windows and vice-versa.

Nice piece of kit. Runs under wine, too.

Notepad is what screwed up the SPICE directives in the Avago files.

Notepad++ is NOT Notepad

I'll repeat my assertion that UltraEdit is the _best_ editor ever.

And it'll do DOS Eunuchs.

I like it because of its macro and scripting capabilities, allowing me to convert _huge_ Spice libraries, in every flavor (and mathematical format) known to man, to PSpice in hours rather than days. ...Jim Thompson

Thanks, Fred, I have bookmarked that. Although I never write code which it seems to be geared towards.
