Abstract
A method includes identifying a timing path in a transistor level from a graph diagram; calculating a plurality of aging costs associated with the timing path based on a plurality of forms of a DC vector; identifying a first form, associated with a first aging cost of the aging costs, from the forms; and identifying a second form, associated with a second aging cost less than the first aging cost, from the forms.
