Abstract:
1. A method to redistribute current demand comprising the steps of: (A) determining timing arc data for one or more timing arcs of a circuit design comprising standard cells using an electronic design tool; (B) checking timing arc data for delay shift target cells among said standard cells and generating a opportunity map indicating one or more delay shift target cells to be replaced by one or more corresponding delay shift cells, wherein said one or more corresponding delay shift cells provide timing budget characteristics that are shifted with respect to the standard cells; and (C) substituting at least one standard cell identified as a delay shift target cell with a corresponding delay shift cell, wherein switching current demand of at least one timing arc is redistributed with respect to a clock period and total current demand of the modified circuit design remains substantially similar to total current demand of the unmodified circuit design.
