Abstract
A method of optimizing signal timing delays and power consumption through multi-path LSI circuits constructed from a plurality of circuit blocks, each circuit block having associated therewith a plurality of power levels which are selectable to control the timing delays through the circuit block, wherein the method steps include the formation of a power-performance derivative for each circuit block, identifying therefrom the relative contribution to signal delay of the circuit block in the entire multi-path configuration, and selecting the optimum power level for an overall multi-path minimum signal delay condition, through a process of iterative calculation of timing delays through individual circuit blocks and multi-path timing analysis.
