Abstract
Methods and systems for allowing an Integrated Circuit designer to specify one or more design rules, and to determine the expected probability of success of the IC design based on the design rules. Probability information is compiled for each circuit component, that specifies the probability of the circuit component working if a characteristic of the circuit component is varied. As the design rules are examined, the probability of each component working is calculated. The probabilities are combined to determine the overall probability of success for the IC design. Furthermore, the IC design may be broken into a plurality of portions, and design rules can be separately specified for each portion. This allows a designer the flexibility to use different design rules on different portions of the IC design.
