20-sim 4C is automatically started when you generate C-code in 20-sim. You can however start 20-sim 4C manually to open existing 20-sim 4C projects or to create a new project with your own models.

Open an existing 20-sim 4C project

1.From the Windows Start menu open 20-sim 4C.

2.From the File menu select Open Project. (A model can only be added to a target in a project.)

You will be asked for a name and location of the project. Alternatively, you can double click on a 20-sim 4C project file in the Windows Explorer (Files with .txp extension).

Create a new 20-sim 4C project

1.From the Windows Start menu open 20-sim 4C.

2.From the File menu select New Project. (A model can only be added to a target in a project.)

You will be asked for a name and location of the project.

3.From the Project menu select Add Target.

4.From the Project menu select Add Model.

You will be asked for a model name with the extension .mcf which stands for model specification file. This is an XML based file that 20-sim 4C uses for a description of the model.
