A Waveform can also be activated directly during a simulation session by selecting Displays > Waveforms. This opens the Waveforms in Workarea dialog box. Select the needed names and click OK for activation. To start a new form, click OK; you are prompted to enter a new Waveform name. In this case, an empty Waveform window is created. Use the Waveform tool facilities to select the elements to be displayed.
