how to via on SC pin with diffrient Net name

ArcherGong

I have created globalNetconnect on PowerSwitch Global Pin VDDG 

  globalNetConnect VDD    -type pgpin -pin VDDG -all

but I can not VIA on that pin from VDD M5 to the PowerSwitch Global VDDG M1 with under command

  editPowerVia -bottom_layer M1 -add_vias 1 -top_layer M5 -net VDD

  • Hi,
    I suggest you isolate the problem first: Is the globalNetConnect not creating a connection for this pin or is the editPowerVia not dropping a via.

    To check that see if the pin is assigned the right net:

    get_db pg_pin:<design><pin_name>/VSS .net.name   -> Is the net correct ?

    If so, you will have to analyze why is this happening. Otherwise, editPowerVia command is not performing as expected for some reason.
    You can try using the option  skip_via_on_pin , in case the power switch is a standard cell :

    editPowerVia -bottom_layer M1 -add_vias 1 -top_layer M5 -net VDD -skip_via_on_pin {}
