Installed by default and available from the Components panel, the Simulation Generic Components
library provides access to various simulation-ready components: from RLC passives through discrete semiconductors to digital components in different formats.
When a component from the Simulation Generic Components
library is placed onto your schematics, select it to access its properties using the Properties panel in its Simulation Generic Component mode. The panel includes the Parameters region from where you can define the values of the component parameters.
Select a placed simulation generic component to define its parameters using the Properties panel.
Use the sections below to find information about the parameters of the components from the Simulation Generic Components
library.
