Title: How to run corner analysis over parameter analysis
Post by Julian18 on Nov 15^th, 2007, 9:34pm

Hi, there:
I try to run Corner analysis over parameter analysis like this

loadPcf("xxxxx.pcf")
parameterAnalysis("id" ?values '(90u 100u 110u))
cornerRun()
cornerMeas()

but the results have no parameter result. only corner simulation result.

How to do a corner analysis over parameter analysis?

Thanks

Hi, I try to overcome this but ....

I think I have done something dumb as shown below
foreach(device '("tt" "ss" "ff")
foreach(element '("typ" "min" "max")
modelFile(
'("/xx/xx/1.scs" sprintf(nil "%s" device))
'("/xx/xx/2.scs" sprintf(nil "%s" element))
)
paramAnalysis("id" ?values '(90u 100u 110u)
paramAnalysis("vd" ?values '(1.62u 1.8u)))
paramRun()
)
)

which does not work, seems that foreach statement can not be nested and the sprintf can not give the model file a right section definition.

Can someone give me some tested script to do all that job? It is such a tedious work to manually write down several hundreds corners definition in a pcf file.

Thanks

You should read manual.

I don't think nested foreach statement can't work.
Rather you should rewrite like following:

modelFile(
list( "/xx/xx/1.scs" sprintf(nil "%s" device) )
list( "/xx/xx/2.scs" sprintf(nil "%s" element) )
)

or

modelFile(
list( "/xx/xx/1.scs" sprintf(nil "\"%s\"" device) )
list( "/xx/xx/2.scs" sprintf(nil "\"%s\"" element) )
)

I don't check which is appropriate. But I think first one is appropriate.
