1. A computer implemented method of selecting a device threshold voltage, comprising the steps of:

  • identifying a critical path through a circuit;

    selecting devices in said critical path according to a predetermined cost function to adjust the threshold voltage of at least one of the selected devices, wherein the cost function includes at least two components, a first component dependent on process parameters and a second component dependent on design specific parameters; and

    adjusting the threshold voltage of said at least one of the selected devices in said critical path to meet predetermined timing criteria.
