The Simulation – General page of the Preferences dialog


The Simulation – General page of the Preferences dialog is used to define the default model path for circuit simulation models and to select the default simulator. To find the simulation models, the software will search the current project's folder first, then search the desired location for referenced simulation models. 


The Simulation – General page is accessed by clicking General under the Simulation folder in the main Preferences dialog (accessed by clicking the  button in the top right corner of the design space).



  • Model Path – click the folder icon to open a dialog to search for and select the target folder that contains the simulation models.


  • Default Simulator – use the drop-down to select the desired default simulator.


  • Always Generate Model Symbol for Manufacturer Part Search Panel Using Simulation Model Description – when this option is enabled, schematic symbols being placed from the Manufacturing Part Search panel to a schematic sheet will always be generated based on the simulation model description of the selected component.
