Abstract: A method of estimating aging of an integrated circuit (IC) includes: obtaining a first process design kit (PDK) including a plurality of first device models corresponding to a plurality of devices provided by a process of fabricating the IC; obtaining values of aging parameters of device instances included in a netlist defining the IC, by performing a first circuit simulation based on the netlist and the first PDK; and obtaining aging data of the IC by performing a second circuit simulation based on the values of the aging parameters and the netlist, wherein each of the plurality of first device models includes at least one measurement command to be executed in the first circuit simulation to calculate an aging parameter.

Abstract: A soft error rate (SER) associated with a design of a semiconductor circuit may be predicted based on implementing a simulation associated with the design. The simulation may include generating a simulation environment based on information indicating the design, performing a particle strike simulation based on the simulation environment to generate charge deposition information, and calculating a collected charge quantity from the charge deposition information. A determination may be made whether the SER predicted based on the collected charge quantity at least meets a threshold. The design may be modified, and the simulation repeated, if the predicted SER value meets a threshold value. A semiconductor circuit may be manufactured based on the design if the predicted SER value is less than the threshold value.
