  •  Hi Kari,

       I have also tried the same way as you have told but did not work, as i wanted a list of pads to be connected to the power domain ring but as the pin names for all the pads were VDD & VSS i was not able to connect the list of selected pads alone using the sroute command,

      so we have to first clear all the golbal net connections & create the ring for the power domain with a different global net (VDD1 & VSS1 ) then define the globalnetconnect command with -pgpin option & specify the pin as VDD & then provide the list of instances (pad instance ) to be connected. 

        This is how it works now.

     

    any way thanks for your suggestions

     

    regards
