Extending a clock frequency range of a critical path monitor

A critical path monitor (CPM) is configured in an integrated circuit (IC). The IC includes a set of critical paths. The CPM includes a set of split paths, a split path in the set of split paths corresponding to a critical path in the set of critical paths, and a split path in the set of split paths...

More Information
Summary:A critical path monitor (CPM) is configured in an integrated circuit (IC). The IC includes a set of critical paths. The CPM includes a set of split paths, a split path in the set of split paths corresponding to a critical path in the set of critical paths, and a split path in the set of split paths including an edge detector. The edge detector is configured with a set of edge detector latches. A set of set-reset (SR) latches is configured such that an edge detector latch is associated with a corresponding SR latch. A reset signal is configured to reach the set of edge detector latches in an offset synchronization with a latch clock signal used in the set of edge detector latches. The CPM is configured to operate using a frequency of the latch clock signal such that the frequency is higher than a threshold frequency.
