To get started with SimPCB Lite, first create a project.

  • Project – A single unit (*.SIMP file) that contains models (structures) and calculations.

Once a project is generated, it already contains a default model (structure) and an empty calculation for this model.

  • Model – A model (structure) of a transmission line or via.
  • Calculation – A calculation performed on a model using specified input data. It defines calculation input parameters, as well as result presentation settings.

Projects panel - New project

You can optionally create groups within a project to combine individual models.

  • Group – An optional folder to combine models according to your logic.
