    摘要: In an embodiment, an aging analysis tool may be configured to identify transistors that are expected to experience aging effects according to worst case stress vectors and/or designer identified worst case conditions. The aging analysis tool may modify a representation of the circuit (e.g. a netlist), replacing the identified transistors with aged transistors (e.g. by modifying parameters of the transistors in the netlist). The aging analysis tool may process the modified netlist over a range of conditions at which the circuit is expected to operate, to ensure that the design meets specifications after aging. The process may be repeated until the aged design meets specifications (with circuit modifications made by the designer to improve the design).

    摘要: A software tool and method for analyzing the reliability or failure rate of an integrated circuit (IC) are disclosed. The IC may include a plurality of circuit designs, and the software tool and method may aid a designer of the IC in determining a reliability rating of the IC based on reliability ratings of transistors or other circuit devices used in the circuit designs. In particular, the IC may include one or more circuit designs that have multiple instances within the IC (i.e., the same circuit design is instantiated multiple times), and the software tool and method may take into account the multiple instances when determining the reliability rating of the IC.
