Preserving Unconnected Nets for Signal Tap

Is there any way of preserving nets that are unconnected to anything other than signal tap? I want to add a counter to monitor another signal that has no other purpose other than viewing in ST.

I have found using the noprune attribute in VHDL doesn't work. However, as the previous post indicates, elaborate the design, then use Signal Tap to add the fanless registers with the pre-synthesis option in SignalTap; then recompile the design, and the fanless registers will be preserved. I have found that this works. -James
