Hello all!
I have a small digital circuit (~200 gates) which is using voltage-
scaling. It was designed in a 0.35um channel length process with ~0.5
NMOS and ~0.7 PMOS threshold voltages. However, when trying to
simulate it with Spectre, the circuit simply doesn't work for deeper
scaling voltages (<1.3V). I am not absolutely sure, but the block
should work properly at this range of voltages, and it sounds more
like a simulation problem than circuit problem. For voltages starting
at 3.3V to 1.3V, the block works quite fine, but starting at this
point, the logic simply stucks. Does somebody have a clue?
