Warnings on POWER and GROUND pins on LVS

When you have warnings during LVS check about power and ground pins like this:


Warning: #3 in pll_ref
WARNING: Invalid PATHCHK request "! POWER": no POWER nets present, operation aborted.


Warning: #4 in pll_ref
WARNING: Invalid PATHCHK request "GROUND && ! POWER": no POWER nets present, operation aborted.


Warning: #5 in pll_ref
WARNING: Invalid PATHCHK request "POWER && ! GROUND": no POWER nets present, operation aborted.


Warning: #6 in pll_ref
WARNING: Invalid PATHCHK request "! POWER && ! GROUND": no POWER nets present, operation aborted.

Go to Calibre - Run LVS - LVS Options - Supply and add names of power and ground pins of your scheme to the Power nets: and Ground nets: fields
