摘要： Systems and methods are provided that can be utilized to estimate power associated with a circuit design. The estimated power is determined by employing power characterizations associated with dynamic and static power related parameters of a circuit design. The power characterizations can be determined prior to circuit design optimizations, stored and utilized during circuit design optimizations.

摘要： Systems and methods are disclosed for selecting a value set associated with a set of parameters. Real costs are generated for each of a plurality of first value sets represented as a plurality of real chromosomes. Speculative costs are generated for each of a plurality of second value sets represented as a plurality of speculative chromosomes that represent value set variations of the first value sets. At least one subsequent generation of speculative chromosomes is generated until a predetermined validation criteria has been satisfied. Upon achieving the predetermined validation criteria, real costs are generated for at least one speculative chromosome of the plurality of speculative chromosomes.

摘要： Systems and methods are provided that can be utilized to estimate power associated with a circuit design. The estimated power is determined by employing power characterizations to determine power consumption associated with non-conventional circuits in the circuit design. The power characterizations can be determined prior to circuit design timing analysis, stored and utilized during circuit design timing analysis. The power estimates associated with the non-conventional circuits can be added to power estimates associated with the conventional circuits of the circuit design to compute a power associated with the circuit design.

摘要： Systems and methods associated with costs of a selected objective are disclosed. One embodiment of a system may comprise a constraint evaluator that evaluates a value set associated with a plurality of objectives to determine if a non-selected objective has violated at least one constraint. The system may further comprise a cost function configurable to evaluate a cost associated with the value set at a first cost range if the value set violates the at least one constraint associated with the non-selected objective, and to evaluate a cost associated with the value set at a second cost range associated with the selected objective if the value set does not violate the at least one constraint associated with the non-selected objective, such that the second cost range is different from the first cost range.

摘要： Systems and methods are disclosed for selecting a value set associated with a set of parameters. A genetic algorithm generates at least one generation of speculative chromosomes that represent value set variations of a plurality of value sets. Each generation of speculative chromosomes are assigned a speculative count corresponding to a speculative chromosome generation. Validation is initiated once at least one speculative chromosome has a predetermined speculative count.

摘要： Systems and methods are provided for selecting a value set associated with a set of parameters. A real cost function generates a real cost for a first value set associated with a set of parameters. A genetic algorithm generates a second value set that is a variation of the first value set. A cost function approximator determines an approximate cost based on the real cost and a value set variation between the second value set and the first value set.
