PSpice is a circuit simulation software package.  PSpice is based on SPICE, but unlike SPICE, PSpice has a user-friendly graphical interface.  This makes PSpice much easier to use for circuit simulation with few circuit elements.  If you are looking to simulate a relatively large circuit, you should probably use SPICE because it is faster and easier to program circuits that will not fit on one computer screen in PSpice.  Also, there is a limit on the number of nodes, active devices, etc. that one circuit in the PSpice evaluation version can simulate.  For more details on these limitations see the release notes.  SPICE serves as a good alternative in the case that the limits for the PSpice evaluation software must be exceeded.  See our SPICE page for more information.  PSpice (evaluation version) is available on all of the Tiger-Lan computer in the engineering buildings.
