Abstract
A method of generating power vectors to calculate power dissipation for a circuit cell is provided. The method involves formulating the Boolean equations (30) that describe the logical operation for a circuit cell (10). Primitive power vectors that cause an output to transition are generated (32) using Boolean difference functions. Internal power vectors that cause an internal node to transition without transitioning the output are generated (34) using Boolean difference functions. Static power vectors with all possible steady state inputs are also generated (36). The power vectors are minimized (38) to eliminate redundant vectors. The resulting power vectors can be used in a circuit simulation in evaluating (40) the power dissipation of a designed logic circuit.
