Popis:	We describe various design automation solutions for design migration to a dual-Vt process technology. We include the results of a Lagrangian relaxation based tool, iSTATS, and a heuristic iterative optimization flow. Joint dual-Vt allocation and sizing reduces total power by 10+% compared with Vt allocation alone, and by 25+% compared with pure sizing methods. The heuristic flow requires 5/spl times/ larger computation runtime than iSTATS due to its iterative nature.
