Hi all,

           I have installed a PDK and set some settings in Switches in DRC form. I have been getting below warnings in CIW while running DRC. 

Warnings:

     Hi Quek,

     Thank you Quek. Problem is solved. Now it works good. Problem is in layout. Previously we added one extra Layer on device which is not required.

    Thank you
