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

     Hello,

     I don't know if this forum still be active, but I want explain a problem I have with the option Excluded Nets.

    I make a lot of big extract with option Selected Net. the selection of net is build from various skill I made to catch the list of all schematics nets (including hierarchical notation), then I reduce the list of net with some regular expressions in order to produce the exact list of net I want to extract. This flow works fine, and I can handle big simulation with/without power supplies, static commands, etc...

    I want to extend this flow with the option Excluded Net, but I'm in face to a big problem since the long time. the extract view created with list of net to exclude is correct EXCEPT for the substrate node. In my design the substrate node (general PTAP connection) is named "gnds" and I always get the extracted view. The only way to not have it in the extraction with Excluded Net option is to use the switch in tab "Extraction" Name Space -> Layout Name. But in that case all the other net that I want to exclude seem to be unrecognized by QRC because I get it in the extracted view.

     

    Does anyone know this problem?

    Thanks
