Dear Andrew (and Holz), [quote userid="4936" url="~/cadence_technology_forums/f/custom-ic-design/49534/change-default-increment-of-deriv/1379438#1379438"]Not sure I get Shawn's point of strobing with 2ps and then sampling with 20ps - that just seems a good way of slowing the simulator down or forcing it to produce more output data than it might otherwise need to).[/quote] My motivation for this comment was to avoid running two simulations - one with a strobeperiod of 20 ps and only saved strobed outputs and a second with a strobeperiod of 2 ps and only save strobed outputs if Holz wanted to examine the output of the deriv() function using both 20 ps and 2 ps x-increments. By running a single simulation with a strobeperiod of 2 ps, and then using the sample() function to sample the 2 ps data at an interval of 20 ps, the need to run two distinct simulations is avoided. I hope that makes a little more sense now. My apologies for my confusing post! Shawn
