How to dump the RDL layer route information, while excluding all other routing layers information in Cadence 9.1.
I need to load that data into new design, where it has same package bump and pad structure.
You can delete all the layers except the RDL, then use defOutBySection to get the right routing section of just the RDL (special route or regular, etc.).
Then read that def into your new design. Don't save the old one, since you deleted the routing. :-)
