Generate SimModel Files

The Generate SimModel Files dialog
The Generate SimModel Files dialog


The Generate SimModel Files dialog provides controls that are necessary to create source SimModel file(s).

Only components in currently-enabled tables will be considered when generating SimModel files.


From the schematic library editor or a standard Database Library (*.DbLib), click Tools » Generate SimModel Files from the main menu.

If using an Integrated Library, simply extract the source libraries through Altium Designer (File » Open), then make the source Schematic Library the active document.
SimModel files cannot be generated from an SVN Database Library (*.SVNDbLib).


Use the Options region of the dialog to determine file generation. First, specify where the generated files are to be stored: either in a sub-folder of the location in which the source Database Library resides or in a specified folder elsewhere.​ By default, a sub-folder named Sim Models will be created. Change this naming to something more suitable as required. If the nominated folder exists, it will be used. If not, it will be created.

Optionally choose to:

  • Overwrite existing files – have existing SimModel files with the same name overwritten when new files are generated.
  • Create folder for each library file – use this option to store generated SimModel files in a sub-folder, named using the source DbLib name. This is beneficial if releasing to a target directory already containing previously released SimModel files.
  • Explore generated SimModel files – open an instance of Windows Explorer, showing the folder containing the generated SimModel files.

After defining options as required, click OK. Generation proceeds and a confirmation dialog appears when the process is complete, stating how many SimModel files were generated. Any referenced .mdl, .ckt, or .scb files will also be stored alongside the SimModel files.

Each SimModel file is named using the name of the simulation model, as specified in the Sim Model Name field for a component record. Where multiple component records (across enabled tables) include the same simulation model implementation – same entry in the Sim Model Name field – only a single SimModel file will be generated, using that name.
