This video is a brief overview of the SPICE capability in Altium Designer. It provides a general understanding of how users would add models to the components and set up and run the analysis.
Altium provides several SPICE-specific libraries that a user will need to provide a stimulus to the circuit (i.e., VDC, sine waves, pulses, etc.). They are generally located in the example directory created during the installation of Altium Designer. This directory path will be similar to C:UsersPublicDocumentsAltiumADxx.xLibrarySimulation, where ADxx.x is a version number.
The 5 libraries provided (all of which are Integrated Libraries):
Simulation Math Function
Simulation PSPICE Functions
Simulation Sources
Simulation Special Functions
Simulation Transmission Line
Install these libraries as you would with any library in Altium.
