Special software is required to use some of the files in this section: .lib, .slb, and .cir.



PSPICE Simulation Information


Download the Microsim (now known as Orcad) DesignLab Release 8 Evaluation version, containing both Schematics and PSpice for PCs. A more up-to-date version can be downloaded from OrCAD.

Spice tutorial (courtesy of University of Pennsylvania Department of Electrical Engineering). In particular, see How to Get Started with PSpice.



(Almost) Ideal Diode Model


idealdiode.lib (LIB) – If you're creating your circuit with the "Schematics" tool, incorporate this library into "Schematics" as follows: Select Analysis -> Library and Include Files. Type the filename idealdiode.lib in the filename box (including the path to the file), and click Add Library. If you're creating your circuit using a standard textfile netlist, add the following lines to your file:

X1 (node 1) (node 2) diode_ideal
.lib idealdiode.lib

idealdiode.slb (SLB) – If you're creating your circuit with the "Schematics" tool, incorporate this symbol library into "Schematics" as follows: Select Options -> Editor Configuration. Select the Library Settings button, and then add the file idealdiode.slb. If you're creating your circuit using a standard textfile netlist, you do NOT need this file.
