Process and environmental variations of CMOS circuits affect product performance and complicate the verification of circuit specifications. In this work a methodology is presented to estimate the impact of process and environmental variations on circuit performance, covering any abstraction level from device to circuit. Beside investigations of delay sensitivities of low-power CMOS technologies from 180nm to 40nm, structural analyses of ARM microprocessors are elaborated to estimate variation-induced delay uncertainty and identify sensitive circuit structures. Using a new definition of robustness which considers structural and topological circuit properties, cost and benefit of various compensation techniques are compared and evaluated.
