Abstract
Systems and methods for applying spatial correlation in integrated circuit development involve placing devices of an integrated circuit design, and obtaining spatial correlation values. Each spatial correlation value indicates a correlation coefficient between a first device and a second device, which are instances of a same device. The correlation coefficient is based on a device separation. Spatial correlation is determined as a function of an inverse of device separation. The device separation refers to one-dimensional or two-dimensional separation. The method includes determining a parameter value for the first device based on an average value of the parameter value and on the spatial correlation as the function of the inverse of the device separation, performing analysis of the integrated circuit design using the parameter value, and providing the integrated circuit design for fabrication into an integrated circuit based on finalizing the design according to the analysis.
