Flexible power query interfaces and infrastructures

摘要

Disclosed below are representative embodiments of methods, apparatus, and systems for performing power analysis during the design and verification of a circuit. Certain exemplary embodiments include user interfaces and software infrastructures that provide a flexible and powerful environment for performing power analysis. For example, embodiments of the disclosed technology can be used to construct complex and targeted power queries that quickly provide a designer with power information during a circuit design process. The disclosed methods can be implemented by a software tool (e.g., a power analysis tool or other EDA tool) that computes and reports power characteristics in a circuit design (e.g., a system-on-a-chip design or other integrated design).

主权项

1. A method, comprising:
by a computer:
allowing a user to create and save a plurality of specifications for a power analysis query without performing a power analysis based on any of the specifications, each of the specifications defining a set of constraints to be used during a power analysis of a netlist for a circuit design or a portion of the netlist for the circuit design;displaying the saved specifications to the user;allowing the user to combine one or more of the saved specifications with each other to form a chained set of specifications; andexecuting a power analysis of the netlist for the circuit design or the portion of the netlist for the circuit design based on the chained set of specifications.
