Solving of spice netlist using Mathcad prime 5.0

Is there any way to generate the voltage and current equations from spice netlist using Mathcad prime 5.0??

It may be possible to do so.

You would have to write a program which reads in the spice file and parses it. Looks like a lot of work.

Guess that calculations would only be possible for simple circuits only, though.

While parsing of the input file may be doable, to actually calculate voltages and currents in a given circuit requires much more. You have to have models and their parameters. Note that models differ between when you do an AC simulation or a TRANsient. If you want to be able to tackle any spice input deck, your effort will be huge, and given the fact that PRIME is not a programming language (!) I think you better crack another nut.

 

This is not to say that it's impossible to calculate electronic circuits, in time or frequency domain.

For a small example:

There's no tool in Mathcad to do this. But there's a free addon for Maple that turns a netlist into equations

Is there any add on for the Mathcad prime like syrup for Maple??

Mathcad from version 4 through 13 uses/used Maple as the symbolic engine. Starting with Mathcad 14, and on to Prime 5 the symbolic engine is MuPad.

 

So: You cannot have Prime use Maple.

 

If you want to use Maple, buy Maple...
