Increase the number of points in a pss

Hello,

I did a pss analysis, with shooting engine and I saw the resulting node-voltage over time. I switched the symbols on and I noticed they are too a few; I would like to increase the numer of points in a period.

How can I do that? I tried to reduce  reltol, vabstol and iabstol in ADE->Simulation->Options->Analog, but the numer of points in a period stays the same.

Thanks!!

    Are you sure you're actually looking at all the points? Turning on symbols in the waveform viewer doesn't show all the points by default - you have to go to the trace properties form and select the show all points checkbox. This is done for performance reasons. 

    The spectre log file ( spectre.out ) should tell you the number of points in the shooting interval.

    Why do you need to increase it? It can be increased but I'd like to understand why you think it needs increasing to ensure that you're not wasting simulation time unnecessarily...

    Now I see... I'm too Matlab oriented :) My mistake was thinking that by just turning the symbols on, I could see all the points. Thank you!!!
