Contents of a Simulation Settings File

You can create a custom text file to override the default simulation settings. This file contains a separate list for each tab of the Simulation Settings form. However, it is not mandatory to specify a list for each tab. You can specify a list for only that tab for which you want to override values. For example, if you need to use custom default values for the EMX simulator only, specify only one list for EMX.

All possible lists with the preset default values are given below.

Example

To use a common set of EMX and GDSView command-line options for all EMX models, create a settings file as shown below.

("EMX"
("EMXCmdLineOptions" "list-of-command-line-options")
("GDSViewCmdLineOptions" "list-of-command-line-options")
)

If you provide the path to this file by using the vem.ic defaultSettingsFile environment variable, cellviews will automatically use the command-line options given in this file when you open the Electromagnetic Solver assistant for the first time.
