Abstract
Methods are provided for optimizing a routing of a signal path in terms of delay and signal integrity in a semiconductor device. The signal path includes at least one track in a metal layer. The method includes selecting an already routed original signal path to be optimized, modifying at least one original routing parameter, creating an alternative signal path based on the modified routing parameter value, determining at least one timing value describing the delay and signal integrity of the alternative signal path and signal integrity, and replacing the already routed original signal path by the alternative signal path based on the timing value indicating that the alternative signal path complies with predefined constraints related to the delay and signal integrity.
