Naturally connecting mixed-signal power networks in mixed-signal simulations

摘要

A system, method, and computer program product for determining whether a design for a circuit meets design specifications, to facilitate the provision of a manufacturable description of the circuit. A computer-operated circuit simulation tool reads the design for the circuit and a power specification, and selectively internally creates a network connection and inserts a corresponding connect module in the design, for at least one circuit block having an unsupported signal declared in the power specification. Typically such a circuit block will be an analog block, whether an original analog block or an analog representation of a digital block, and may involve electrical or wreal signal interactions. The simulation tool performs a mixed-signal simulation of the design. Embodiments tangibly output a verification determination from a comparison of the simulated design performance results and the design specifications in order to provide the manufacturable description of the circuit.
