Creating power\ground pins for digital modules

Tom Urkin

Hello all,

I have two digital modules created in Cadence DC tool. When I import them to Virtuoso (as Verilog files) they have no VDD and GND pins. In this case i use VDD! and GND! as the power and ground rails for simulation.

However, I would like to separate the power nets - one module will be fed from DC rail V1 and the second from power rail V2 (each module has it own power nets which are not connected).

For that I need to create power and ground pins for each digital module. 

How can do this? Other suggestion are most welcomed. 

Thanks!
