A system and method for the adjustment of history based delay variation during static timing analysis of an integrated circuit design. The method may include obtaining information through sources of variability of history based components of delay variability, and a relationship between the sources of variability and one or more bounded device histories. Then, inputting history bounds for at least one signal of the integrated circuit design, and computing and propagating history bounds through at least one first segment of the integrated circuit design to at least one signal of the integrated circuit design. Further, the method may include evaluating from at least one of the propagated history bounds, device history bounds for at least one second segment of the integrated circuit design, and based on the evaluated device history bounds, adjusting at least one of a value of the history based delay variability and propagation of timing. |
