Just curious, I have Calibre tool for check almost everything of physical verification. But I still need more extraction check from diva tool.

For the one who does not know.
We can extract a signal from layout with diva rule. For example I would like to check all METAL and VIA layer of VSS signal. I will write a diva rule and put it in Verify - Extract to generate an other cell which contains all layer of VSS signal.

But could anyone tell me what is diva stand for? Is it Dynamic Identity Verification Authentication?
 

We used to use Diva and I never knew whether it
"stood for" anything, or was just a trade name for
-D-esign -V-erification family.

You could also look at simply doing the extraction,
select-by-net-name, copy to new cellview, and
there's your net all by itself. With no need to write
a script.

Thank you for sharing.

I know. But it has some cons. For example when my big layout is mess up with connection, the highlight net will mark incorrect. When I just want the Metal and Via layer only. Or when I want the output net is merged to Polygon shape, not Path shape.
I tried some options which are built in Cadence but it does not enough for me. So I have to use script.

Do you know any other method to achieve it?
