PSpice Tutorials

In the installation of PSpice some circuits are already included as examples. The examples can be found in the menu under Help > Learning PSpice. Each of these examples explain in English the theory of a circuit and gives a step-by-step guide to simulation. The circuit diagram and the simulation models are all already installed and can be used immediately.

PSpice Reference Circuits and Examples

Below you see a selection of basic electronic circuits. There is a link for a video tutorial, which describes the behaviour of this circuit. The circuit is ready for simulation in PSpice and can be downloaded for free as a .zip file. You can easily reproduce the circuit simulation results and exchange components and settings to better understand the circuit for your own education.

Recommended Literature

FlowCAD is often asked which books about PCB layout or signal integrity are recommended. We have listed here some books that our application engineers have read themselves and whose content we subjectively consider to be useful. This list is not exhaustive and FlowCAD has no commercial use for these book recommendations. If authors think that their books should be included here, please send us a preview copy. We will read and include it here if necessary.
