Method and system for synchronously initializing digital logic circuits

Abstract

A digital system in a first clock domain synchronously initializes a logic circuit having a memory characteristic. The digital system includes first and second logic circuits. The first circuit includes an asynchronous port for receiving a reset signal from a second clock domain, a port for receiving a first clock signal for the first clock domain, and an output port for providing an initialization signal. The first circuit sets the initialization signal at a first logic value in response to the reset signal and maintains the first logic value at least until the first clock signal becomes active. The second circuit includes a synchronous port for receiving the initialization signal, a port for receiving the first clock signal, and a data output port outputting a data signal. The second circuit is initialized in response to the active first clock signal when the initialization signal has the first logic value.
