    DDR3_VTT voltage selection


      I have a .HYP board file for my design, and I exported a free form schematic of one of my DDR3 address lines.  It was terminated to GND thru a 30 ohm resistor, so I changed the ground symbol to DDR3_VTT, but underneath the "DDR3_VTT", it says "0V", and obviously my simulation doesn't work properly with the net terminated to 0V rather than 0.75V.  How can I modify that symbol to give the correct termination voltage?
