Yes, I have in the past, but not recently.
It was done for comparing the connectivity data from one of the
gschem(1) derived file formats, and, the connectivity data from pcb(1)
after manual massaging of the layout. Text program scripts were used
for layout vs. schematic ERC.
I was concerned with inadvertent shorting/bridging of nets, and the
design was large enough that I was concerned about missing something
during manual highlight circuit tracing.
It was for low noise, wide bandwidth, linear/analog designs where the
ground system required a lot of manual intervention.
More recently, on smaller designs, I just manually place components
connected to the '-' input of opamps in close proximity, and
autoroute, depending on the pcb(1) program for correctness.
A layout vs. schematic net checking tool is a nicety, but maybe not a
necessity, IMHO.
