Insert
When the Insert option is selected, a list of all labels assigned in the Format
menu appears. Select the desired label to insert. Select to insert a single bit,
all bits in sequential order, or all bits as a Bus in an overlaid form. The new
inserted waveform is placed directly below the cursor.
Viewing State Values in the Bus Option When all assigned
waveforms in a label are overlaid with the Bus option, the value of the
data is displayed to the right of each new transition in the waveform
display. This will happen only when the waveform size is set to large.
If the sec/Div is set to view a large increment of time, or the waveform scaling
is set to small or medium, the state data readout will not fit between
transitions. To display the state data readouts within the waveform, expand
the sec/Div and use the large waveform setting. If symbols are assigned to
represent data values, the symbol is displayed.
