using globalNetConnect to define a signal as a power source to part of a design

docdrew

I have no issue connecting my VDD and VSS (pwr/gnd) to my macros and std cells, but in this current iteration of my design, I have a SRAM and 45 std cells that I need to connect to a different power source.  The issue is that the power source, called VDD2 is an input from one of the I/O pads.  Every time I use

globalNetConnect VDD2 -pin VDD -type pigpen -inst "instance path/*" -override

but when I run sroute with just the area I fenced these cells into after placing rings and stripes, the VDD pin in the SRAM still only wants to connect to VDD, my global VDD and not the signal power source VBATT I am trying to attach it to.  Any help would be appreciated.
