Abstract:
An engineering change order (ECO) modifying an IC having spare cell instances is implemented by converting active cell instances implementing portions of the IC to be deleted into additional spare cell instances, by creating a technology independent behavioral model of portions of the IC to be added, by selecting spare cell instances to implement the behavior model, and by routing nets to the selected spare cell instances in a way that minimizes a number of metal layers of the IC that are modified.
