Editing the waveforms automatically creates a command file of the ViewTrace waveforms. Execute this command file can during simulation to define input waveforms as follows.
Any output waveforms that remain in your new command file are forced onto your simulation outputs and can cause false results when you run the file.
If you want to reload the waveforms and edit them at a later time, use the File Save As Savefile command to save the waveforms as a stimulus.see file.
