It may be may be convenient to place a D/A interface on digital outputs in order to view those signals. They may be considered as voltmeters attached to the schematic. This will allow for the output voltage to be set separately from the digital 0=0V and 1=1V. The scaling can also be changed by double-clicking on the graph and using the "Signals" tab.
Waveform plotting for digital signals is also limited in that offset voltages must be manually selected and set if it is required to place non overlapping traces
The digital library is somewhat limited at the current time. However, it is relatively straightforward to add additional models and symbols.
Operating Point/Multiple runs
Different run types in one go can not currently be run, if there are XSpice digital components in the schematic. You must enable operating, trans and dc runs one at a time.
