Abstract: A system-on-chip includes first and second devices. An interconnect segment couples between the first and second devices. A bridge is coupled between the first and second devices and coupled to the interconnect segment. At least one of the bridge or interconnect segment include first and second multiplexers, a monitor circuit, and exclusive-OR logic. The first multiplexer has first and second multiplexer inputs and a first multiplexer output. The second multiplexer has third and fourth multiplexer inputs and a second multiplexer output. The monitor circuit has a first and second monitor circuit outputs. The first monitor circuit output is coupled to the second multiplexer input and the second monitor circuit output is coupled to the fourth multiplexer input. The exclusive-OR logic has first and second exclusive-OR logic inputs. The first exclusive-OR logic input couples to the first multiplexer output and the second exclusive-OR logic input couples to the second multiplexer output.
