Assura QRC exclude nets

stuso

Hi there,

this is probaly an easy Q for you guys but is it straight forward to exclude specific nets from assura QRc extraction? I guess it's possible to to this with R or C or RC extract as well.

Looking at the QRC Run Form and "extraction" tab i see an option for Net Selection Type with a few options:

Full Chip All Nets

Full Chip Selected Nets

 ...etc

so it seems logical thet "Eluded Nets" might be the option i require. But next to this there is  another field for "QRCFS Extraction Mode" Shoud i alter this?

Then i assume i should then select from schematic all the nets i want to exclude.

We are playing about with this & reading the manual but its not working as we expect, any suggestions are welcome.

Thanks

Stu

     Hi Quek, thanks for your feedback. Yes i have now read the manual (the first thing i always suggest to others is read the manual), so sorry for the silly q's.

    The option that might help us is selected nets proper. Given the schematic in question is not huge its easy to select say 2/3 of the nets that we want to extract....i tried this and the netlist looks correct with only the R&C for the chosen nets present.

    I've not yet tried excluded nets proper but that might be the option we go for in bigger cells where its more practical to deselect 4-5 nets such that they are not extracted.

    Many thanks

    Stu
