Abstract
An apparatus and method of compensating for differences in circuit routing path lengths is described. In one embodiment, a latch is inserted between reset signal generating logic and a pair of flip-flops. When a reset signal is generated, the reset signal is held inside the latch until both flip-flops are reset. A latch reset signal may be generated by the flip-flops to clear the latch. The circuit may be configured to ensure that both flip-flops are reset before the reset signal is disabled.
