Abstract
This disclosure relates to signal observability rating. In an example, a method can include propagating a clock signal through a respective module of a circuit design in a forward and backward direction, evaluating clock signal propagation results for the respective module based on a forward and backward clock signal propagation of the clock signal to compute an observability rating for a data signal to be processed by the respective module during formal verification, and updating a current observability rating of the respective property for the data signal to the computed observability rating.
