Can RTL Clock Power Be Accurate Enough For Sub-20nm Multi-GHz Designs?

The Register Transfer Language (RTL) has increasingly been adopted to enable early and high-impact power decisions. As a cycle-accurate hardware abstraction, RTL is expected to deliver reasonable power accuracy. Clocks are particularly important to analyze and optimize for power. They switch the most and drive the highest loads. Clock gating is an effective power reduction technique that shuts ... » read more
