Abstract
Method and apparatus for phase-timing compensation is described. More particularly, a clock source and a clock sink of a path are identified for phase-timing compensation for a design. An absolute path slack is obtained, and phase offset of the clock source relative to the clock sink is determined. A normalizing factor responsive to the phase offset is generated. A normalized slack is computed using the absolute path slack and the normalizing factor.
