3.4 Stimulus Window

Use the Stimulus window to create asynchronous or synchronous stimuli. This interface allows you to enter stimulus information which is saved in a file called a workbook.

To open the Stimulus window, select Window>Simulator>Stimulus.

Note: The Stimulus window must be open for stimulus to be active during simulation.
The Stimulus window tabs and tab-related content are discussed in the following sections.
Note: When setting up multiple tabs, be aware of input interaction.

The buttons on the left side of the window have functions you can view by hovering the mouse over a button.
