Virtuoso layout: How to change many shapes from one layer to another at once?

bjbit

Hi all,

This may be a dumb question. But for example: how can I change hundreds of shapes in Metal1 to Metal2 in an easy way? I am using IC61. Thanks in advance.

Best regards,

  • Hi Andrew,

    Thanks a lot for your help. The property assistant is very useful. If you don't mind, may I ask another question?

    I am working on IBM_7RF technology. Now I have to change the top metal layer of my design from ML to AM. That causes the issue that I have to reinstall another PDK and create another workspace for the new top metal layer option, which basically means a new technology version. What I do is copy my design library folder into the new workspace and re-define cds.lib, and then change metal layer of the shapes. When this is done, I tried to test Assura DRC and LVS. Both give errors about "failed on building up VDB". Is the reason from compatibility of my design, or from the Assura itself? I am using IC614 with Assura41. Thanks again for your time.
