1. A method, in a data processing system, for determining failure rate of a device using importance sampling reuse, the method comprising:
performing, by the data processing system, a uniform distribution sampling over a random sample space for a performance metric for the device with respect to an origin to form a uniform distribution set of samples; determining, by the data processing system, an importance sampling weight function based on the origin and the uniform distribution set of samples; determining, by the data processing system, a new importance sampling weight function with respect to a new origin, wherein the new origin represents alternative values for device parameters corresponding to a process variation or design consideration; and determining, by the data processing system, a failure rate for the device using the uniform distribution set of samples and the new importance sampling weight function for the alternative values for the device parameters. |
