Sensitivity simulation from ocean file on extracted view

raduionescu

Hello,

I am not sure this is the right forum for this, but I am running a sensitivity simulation from an ocean script. My issue I have a hierarchy in which one of the blocks is a parasitic extracted view, and I have issue if I try to use a parasitic output net.

I am building a line like

analysis('sens ?anaName "sens"  ?analyses_list list("dc")    ?instances list( ... here I add what I need )     ?net list("/VI"        "/VQ"    "/I1/I_extract/22:Vref_1V5"    )  )

I get sensitivity results in the dcOpSense psf for VI and VQ but not for the parasitic net and in the log I get the warnings

\o     WARNING (SPECTRE-8290): `I_DUT.I_S3732A21.22\': Not a signal, device
\o         instance, or a model.
\o     WARNING (SPECTRE-8293): Ignoring invalid output item
\o         `I_DUT.I_S3732A21.22\:Vref_1V5' in sensitivity request.

I assume I need to somewhow escape the : character but I am not sure how or where to look in the documentation. Does anyone have an idea? Thank you.

Regards,

Radu

    Hi Radu,

    This would be best handled through support.cadence.com because there's guesswork otherwise, but I'd try either "/I1/I_extract/22\\:Vref_1V5" or "I1.I_extract.22\\:Vref_1V5".

    Note I've not tried a similar example, so this is a bit of a guess.

    Andrew.
