no stamped connections
I am layout a POLY resistor in the tsmc 0.18 um proc. The DRC gives me no error, but when I extracted, this error "no stamped connections" persists. I googled for it, without much info. But I just know that it is caused by the lackk of connectino with the substrate. But there are only two terminals of metal 1 in the layout of the resistor, with a layer of poly 1 between these terminals. I cannot find any layer that should be hooked with the substrate.
Any advice? Thanks!
