how to output simulation waveform

[at]

Anyone knows how can I save the simulation output into a readable format
like comma seperated values or something that I use a different software
to plot the output? Do I have to write an ocean script to dump out the
data and then save? My current hack is to do it with ocean script (which
is terribly slow.)

out = outfile("./paramResults.out" "w")

for(tt 1 1000
time = tt*0.001 - 1*0.001
fprintf(out "%5.3f " time) ; Print the time stamp
fprintf(out "%1.6e \n" value(getData("/N2/D" ?result "dc" ),time))

)


Thanks!

Search for abWriteOutputsASCII in comp.cad.cadence and you will find a
little procedure that may help you.

Also, with recent wavescan versions, you can produce a table for any waveform,
and then save that as csv - doesn't help if you want to do it from OCEAN, but if
you merely want to do it interactively, then that can help.

In addition to Svenn's suggestion, you can also use the ocnPrint() function -
you might want to avoid using a fixed step, because otherwise it has to
interpolate. If you really want the steps on a regular grid, and you're using
spectre, use transient strobeperiod option to place a timestep at a regular
interval and output at these solved timesteps
