Abstract: Provided are a method and a system to distribute clock signals in digital circuits to ensure that the multiple clock signals reach multiple loads associated with the digital circuit, concurrently. To that end, an off-chip set of clock paths, which includes one or more clock buffers, are connected between two sets of clock paths on an integrated digital circuit. The multiple clock signals are routed to the off-chip set of clock paths to reduce, or remove, propagational delay in multiple clock signals that arise from the propagation of the same through the on-chip clock paths. This is achieved by the clock paths of the off-chip set of clock paths having differing resistivities, differing lengths or both.

Abstract: A method and apparatus for synchronizing an asynchronous signal to a clock signal. The apparatus includes an enable generator, first, second and third sampling circuits, a selecting circuit, and can include a latching circuit. The enable generator is coupled to the first sampling circuit by a first enable line, to the second sampling circuit by a second enable line, and to the third sampling circuit by a third enable line. The first, second, and third sampling circuits are coupled to receive the asynchronous signal. The selecting circuit is coupled to receive the output signals of the first, second and third sampling circuits. For the first sampling circuit, the following steps are performed: sampling the asynchronous signal, generating an output signal for the sampling circuit, waiting a period of time, and selecting the sampling circuit's output signal. These steps are also performed for the second sampling circuit and the third sampling circuit.
