hello,everybody:After I use the sensitivity analysis in ADE L, I print the sens result in the result box. Then, I found that the sensitivity result is given by S(F,P)=dF/dP rather than S(F,P)=P/F * dF/dPAnd, after I search it in many references, I find that the value of senstype would deside which formula will be used.But unfortunately, in sensitivity analysis ,defaultlly, the senstype=partial,which use the first formula.if you want to use the second formula, you need to spectify that senstype=normalized .But, I donot know where and how to change this value. Could anybody help me?
Have you tried this line in your .cdsenv:
spectre.opts senstype string "normalized"
or adding this line in your .cdsinit
envSetVal("spectre.opts" "senstype" 'string "normalized")
You can query your present value of these from the CIW by entering:
Hope this helps
In reply to SharksFan:
In the UI, it's under Simulation->Options->Analog (in IC5141 it's near the bottom, in IC61X it's on the Miscellaneous tab). It's not under the sens analysis as an option, because sens is actually a control statement rather than an analysis in spectre (so doesn't have any direct options - so it appears under "spectre -h options" rather than "spectre -h sens").
But your expression doesn't wok.
In reply to Andrew Beckett:
You are correct. Now the results is listed in the form of senstype = normalized.
