Abstract
A reduced cell library includes substantially fewer cells than a complete cell library used to finalize the integrated circuit design. More particularly, each cell in the reduced cell library may be characterized by a first drive strength which is the same for each cell in the library. The reduced cell library can be used to evaluate the RTL description of an integrated circuit without incurring long synthesis delays. Large problems in the RTL description (with respect to one or more design goals) may be detected, and the RTL description may be modified to correct the problems.
