ABSTRACT:
A method for evaluating a logic state of a design node involves compiling a logic design to generate an annotated symbol table and a levelized design, obtaining a logic evaluation cost from the levelized design, locating a strategic node using the logic evaluation cost, marking the strategic node, and computing the logic state of the design node using the annotated symbol table, the strategic node, and the levelized design.
