Making diagonal/tilted trace lines (or dummy line) in wavefo

[VINAYRAO M.M]

Hello all,
How one can make diagonal/tilted trace lines (or just a dummy line) in waveform graph XL of cadence? Diagonal traces are very much useful for measuring parameters like Vth or Early voltage (VA). I find only horigontal/vertical/delta traces. To do the required measurement like VTh one has to export the data to Matlab.

I am using IC614, whether this version supports AWD option? (I am not finding option of selecting AWD other than default wavescan in session->options)..



Regards,
Vinay Rao

You could put the x-y pairs in a file and then use the "getAsciiWave"
function in the calculator to read it and produce a waveform.

AWD does not exist in IC61; AWD is ancient technology and has not been
ported to the IC61 release. So there is no choice provided to use it.

I'd strongly advise using IC615; there is a new graph (implemented
natively in Qt) which replaces the Java (based on wavescan) graph that
is in IC614. It's significantly better than both AWD and the IC614 graph
(or wavescan in IC5141).

Andrew.

Thanks for your reply Andrew. You said of putting x-y pairs whether that means saving the waveform (Trace->save->.vscv)? I did that and opened that .vscv using "getasciiwave" of calculator. Then it opened again in AWD where I can't draw any diagonal lines in that. We dont have license to go for IC615.

Your question is not very clear - I was suggesting writing the values by
hand in an ASCII file and reading that. If you're exporting the data and
then re-reading it, I'm not sure what you're expecting...

There's no need to use IC615 to do this - you can do this in any version.
