Abstract
A computer-implemented method of determining threshold voltage levels within a macro of integrated circuit cells. In one embodiment, the method includes: referencing a library of the integrated circuit cells in the macro; estimating a leakage power and a dynamic power for a first integrated circuit cell in the macro; comparing the leakage power with the dynamic power; switching the first integrated circuit cell to a low threshold voltage level in response to determining the dynamic power is greater than the leakage power; and updating the library with a voltage level of the first integrated circuit cell.
