Classification: CPC G | IPC G

Claim 17:
18. A method of estimating aging of an integrated circuit (IC), the method comprising:
obtaining a first process design kit (PDK) comprising a plurality of first device models corresponding to a plurality of devices provided by a process of fabricating the IC; and
performing a first circuit simulation based on a netlist and the first PDK to obtain values of aging parameters of device instances included in the netlist defining the IC,
wherein the obtaining of the first PDK comprises:
obtaining a second PDK comprising a plurality of second device models comprising model parameters defining operational characteristics of the plurality of devices, respectively;
obtaining an aging library comprising a plurality of measurement commands to calculate the aging parameters, the plurality of measurement commands being executed in the first circuit simulation and correspond to the plurality of devices; and
generating the first PDK by adding at least one measurement command to each of the plurality of second device models based on the second PDK and the aging library.
