It was gut-wrenchingly awful to write, but worth every drop of frustration and every last hate email. WebUsing Voltus or Redhawk, a chip designer verifies that his IR-drop is within X% of the supply voltage and then in Tempus (or Primetime) he checks to see that his worst-case timing signoff is verified with that X% reduction in the supply voltage. Each analysis is done separately and often by different people.
