1. A method of designing an integrated circuit, comprising: generating, using a computer, a functional design for said integrated circuit; determining performance objectives for said integrated circuit; determining an optimization target voltage for said integrated circuit; determining whether said integrated circuit needs voltage scaling to achieve said performance objectives at said optimization target voltage and, if so, whether said integrated circuit is to employ static voltage scaling or adaptive voltage scaling; using said optimization target voltage to synthesize a layout from said functional integrated circuit design that meets said performance objectives by employing standardized data created by designing at least one representative benchmark circuit, establishing standard sensitization and measurement rules for delay and power for said at least one representative benchmark circuit and across corners in said technology nodes, performing a simulation by sweeping through a range of values and at predetermined intervals across said corners, extracting data from said simulation, and parsing and interpreting said data to produce at least one report; and performing a timing signoff of said layout at said optimization target voltage.
