As a schematic editor, OrCAD allows you to draw circuit schematics. The program has a nice collection of circuit parts or components to allow you to perform their assignments and laboratory exercises.
PSPICE is an electrical simulator that allows you to model the operation of circuits whose schematic was prepared using ORCAD. Students can now check for correct circuit operation before building the circuit in the lab.
The student version of ORCAD runs PSPICE without leaving the user interface of ORCAD.
