Designs have become more complex, voltage aware DRC is important for today's complex designs with multiple voltage signals. It's getting more
critical with scaling down the technology, as the number of voltage aware DRC rules increases with advanced nodes. Calibre PERC has a
complete automated way using the static voltage propagation technique to propagate the voltages across the design and apply a certain spacing
rules based on the voltage condition, and report all the violation in Calibre RVE for easy debugging.
