Waveform units?

QSPICE

Hi All,

I am wondering what are the supported waveform units in qraw?

I have checked that by default its always voltage or current for branch current and node voltage.
in qraw, it is written as:
v(n02) voltage
i(c1) current

and actually we can easily change the unit on the waveform viewer by editing the .qraw file in Notepad++, i.e.:
v(n02) power or v(n02) frequency, then when you plot that node the waveform viewer will use (W) or (Hz) on the vertical unit

Just curious about other units?

So far, i notice these units:

  • voltage
  • current
  • frequency
  • power

And is there anyway set this unit from the schematic viewer instead of need to tinkering on the Notepad++ and also avoid needing to redo it everytime we run the simulation.

Super Kelvin to the rescue… Thanks a lot
