The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to access the Source Data dialog, from where you can define the list of possible source simulation waveforms that can be used in the active chart.


This command can be accessed from the SimData Editor in the following ways:

  • Choose the Chart » Source Data command from the main menus.
  • Click the  button on the SimView toolbar.


After launching the command, the Source Data dialog will open. The dialog lists all source simulation waveforms that can be used with the active chart.

Click the Create button to open the Create Source Waveform dialog in which you can define a new waveform by entering a series of XY value pairs for a series of data points or create a custom sine, or pulse wave.

The Source Data dialog also enables you to store any of the waveforms as ASCII text files (<WaveformName>.wdf). These waveform files can be recalled and loaded into the list at any time.


The dialog allows editing of user-defined waveforms that have been manually created and not those that have been generated as a result of design simulation.

A .wdf file contains the waveform as a series of data points, each represented by an XY value pair.

The list of possible source simulation waveforms that can be added to the active chart are also listed in the Source Data region of the Sim Data panel. The panel also provides access to the Source Data dialog by clicking the Source Data button.
