LTspice Question:

I have a client using LTspice.

What is the best way for him to import a design from PSpice?

Would it work if I make my schematic into a SUBCKT that includes the
device models within the subcircuit?

Hire a consultant to help you, cheapskate.

Hello Jim,

Yes this may be OK. LTspice is very compatible to PSPICE
except for digital devices.
Why making a subcircuit? Just run the netlist as it is.

Best regards,
Helmut

I suspect that at the level of simulation intended, the digital
devices ARE analog.

Give them the .CIR and .NET files. The .CIR file calls the .NET file.
LTspice will run the .CIR file without problem if you don't have any
goofy digital blocks.

Be sure to give friendly net names to all the points they want to
probe. Sucks having to search thru the net list for names.

That's what I sent them while I think about it, and I just got an

Indeed.

My first physics professor, who used to refer to a uniform bar as a

Digital units all have the tendency to be quantified and constant. Until
the not so digital stuff strikes. Ground bounce, ringing, crosstalk,
EMI, magnetic coupling, supply glitches, the sales guy answering his
cell phone and so on. Then they call on us analog dudes again ;-)
