how to delete via cell in the design

c1irfana

Hi,

Two questions:

1) Does anyone know how to remove via cell from the design??  These are in the design but NOT from  LEF.  

2) Also once you add NDR rule. Is there a way to remove it in the db??

Thanks,

Irfan

  • I don't think you can delete an NDR during an innovus session. You would have to edit the tech LEF then reread the design in a new session, making sure that the NDR you deleted is not used anywhere in the design. For vias, if they are not in the LEF, then you have to find out where they are coming from and maybe you can do something similar.
