A relationship between at least a first metric of an integrated circuit (IC) design and a power supply voltage of the IC design may be determined based on a set of IC designs that have different power supply voltages. Next, the power supply voltage and at least the first metric of the IC design may be modified by interpolating values of the first metric based on the relationship between the first metric and the power supply voltage of the IC design.

Co-optimizing power supply voltage in an integrated circuit design

An efficient electronic structure for circuit design, testing and/or manufacture for validating a cell layout design using an intelligent engine trained using selectively arranged cells selected from a cell library. An initial design rule violation (DRV) prediction engine is initially trained using a plurality of pin patterns generated by predefined cell placement combinations, where pin patterns are pixelized and quantified and is classified as either (i) a DRV pin pattern (i.e., pin patterns likely to produce a DRV) or (ii) a DRV-clean pin pattern (i.e., pin patterns unlikely to produce a DRV).

Pin accessibility prediction engine

Roughly described, a method for synthesizing a circuit design from a logic design includes developing candidate solutions for a particular signal path, a first candidate solution identifying a first library cells followed immediately downstream thereof by a first set of zero or more buffers, and a second candidate solution identifying a second library cell followed immediately downstream thereof by a second set of zero or more buffers, the first library cell and first set of buffers in combination being different from the second library cell and second set of buffers in combination. The computer system selects among the candidate solutions at least in part in dependence upon sensitivity of the solution to load capacitance in the particular path, and stores the selected solution in the storage for subsequent use in further developing and fabricating an integrated circuit device.
