Abstract

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.

Description

technical field [0001] The present disclosure is about a design method of an integrated circuit. Background technique [0002] The semiconductor integrated circuit (IC) industry has experienced rapid growth. During the evolution of integrated circuits, functional density (ie, the number of interconnected elements per wafer area) has increased while size (ie, the smallest element (or wiring) that can be produced using a manufacturing process) has decreased. The advantage of this shrinking process is to increase product efficiency and reduce related costs. [0003] Another aspect of IC evolution includes increasing the complexity of IC design and shortening time-to-market. Designers generally face an engineering schedule from IC concept to IC production. To meet these challenges, designers typically start with simulations of the IC design and check the performance and functionality of the IC design as thoroughly as possible before finalizing it. Realistic simulations take ...
