Files Needed for

Simulation

To simulate your design, PSpice A/D needs to know about:

• the parts in your circuit and how they are connected,

• what analyses to run,

• the simulation models that correspond to the parts in your

circuit, and

• the stimulus definitions to test with.

This information is provided in various data files. Some of these

are generated by Schematics, others come from libraries (which

can also be generated by other programs like the Stimulus Editor

and Parts), and still others are user-defined.

Schematics-Generated Data Files That PSpice A/

D Reads

When you begin the simulation process, Schematics first

generates files describing the parts and connections in your

circuit. These files are the netlist file and the circuit file that

PSpice A/D reads before doing anything else.
