Routing Closure Challenges At 28nm And Below

As I described in my last article, the gap between router tech files and signoff rule decks at 28 nm and below is generating some serious impacts on tapeout schedules. The mismatch between the router’s simplified tech file and the complex rules that represent the intricate manufacturing requirements at these leading-edge nodes means designs that come from the router “DRC/DFM-clean” will, ... » read more
