I am trying to generate a plot of one of the capacitance values generated by captab. My approach is as follows:
1. Use stimulusFile to include the instruction: Cap_dcInfo info what=captab detail=nodetonode sort=name threshold=0 where=logfile
2. Set up captab analysis: Analysis( 'dc ?captab t ?detail "nodetonode")
3. Run parameteric analysis across voltage to generate multiple cap. tables:
paramAnalysis( "vdd" ?start vstart ?stop vstop ?step vstep)
This seems to work when I only run step 2 and 3 meaning I see the multiple cap. tables in the spectre.out file. However, I am having trouble figuring out how to plot a specific capacitance value from the generated tables with the independent variable being "vdd". Although an example exists in a previous post http://www.cadence.com/Community/forums/p/21764/1309486.aspx, it does not include the stimulus used and it did not attempt to plot multiple values but rather only print a single value.
Any help will be greatly appreciated.
