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

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.
