In the newer versions of Virtuoso, there is an option in the LSW for Layout where you can select only the routing layers. Are the routing layers basically the metal layers - ie. M1, M2 etc in the PDK ? I want to use this feature in the older version of Virtuoso I have so I wanted to check what this function did. Thanks.

Click to expand... routing layers are a function of the technology and metal stack. in legacy nodes, poly was routable. these days you have some M0 layers that are routable, some that aren't. Some M1 layers are restricted, etc.
