An integrated circuit (IC) design method includes receiving a spatial correlation matrix, R, of certain property of post-fabrication IC devices; and deriving a random number generation function g(x, y) such that random numbers for a device at a coordinate (x, y) can be generated by g(x, y) independent of other devices, and all pairs of random numbers satisfy the spatial correlation matrix R. The method further includes receiving an IC design layout having pre-fabrication IC devices, each of the pre-fabrication IC devices having a coordinate and a first value of the property. The method further includes generating random numbers using the coordinates of the pre-fabrication IC devices and the function g(x, y); deriving second values of the property by applying the random numbers to the first values; and providing the second values to an IC simulation tool.

Method and system for integrated circuit design with on-chip variation and spatial correlation

A method includes receiving input information related to devices of an integrated circuit. A first simulation of the integrated circuit is performed over a first time period. Average temperature changes of the devices over the first time period are calculated. A second simulation of the integrated circuit is performed over a second time period using the average temperature changes of the devices. The first simulation and the second simulation are executed by a processor unit.
