Abstract
Approaches for generating delay values for instances of a circuit include inputting possible contexts of the circuit. Each context includes a respective delay value and a combination of possible types of a plurality of characteristics of the circuit, and each characteristic is of one type of a plurality of alternative types of the characteristic. A plurality of classification parameters is input and the classification parameters indicate selected ones of the characteristics. Groups of contexts are selected based on the plurality of classification parameters. Each group includes one or more of the contexts, and each context includes the plurality of characteristics. A combination of types of the selected characteristics in each context in a group is equal to the combination of types of the selected characteristics of each other context in the group. For each group, a mean and a standard deviation of the respective delay values are determined and output.
