Title: I can't understand this error in IC610 Post by sutapanaki on Oct 20th, 2009, 4:33pm Hi, I'm trying to plot the gds parameter of a MOS transistor during DC sweep. I have done "save M:oppoint" and simulation goes ok. Then from results browser I'm able to plot gds vs. the sweep parameter in wavescan. What I wanted to do next was to input this waveform in calculator, do some processing, namely namely get the reciprocal of it (1/gds) and plot again. When I tried to plot it from within calculator though, I got the following error: - Warning - <Calculator> Evaluation error(ERROR : ("quotient" 0 t nil ("*Error* quotient: can't handle (1 / nil)"))). Expression: 1/getData("/MN:gds" ? resultsDir "/home/simulation/HW4_pr3/spectre/schematic" ?result "dc- dc") - Warning - <Calculator> Evaluation error(Unknown scalar data type: nil). Expression: getData ("/MN:gds" ?result "dc-dc") As far as I understand it, it says that the waveform is 0 (nil). However, I just got the waveform from wavescan, so it can't be nil. Even if I try to put it in the calculator from wavescan and immediately plot back from there, without any processing it still gives the same error. I tried doing the same procedure on a regular AC analysis, just plotting node voltages from results browser and from calculator. It works without a problem. Can anyone help, please? Thanks |
