Abstract
A system may be employed for allowing the synchronous operation of an asynchronous system. The system may be a system that may include multiple clusters. The clusters may include asynchronous clock domains and may also receive a global clock signal through a global clock grid that may overlay the system. Furthermore, a method may be employed for synchronizing asynchronous clock domains within a cluster. The method of synchronizing may include providing a global clock that corresponds to a global clock grid to each cluster. Additionally, the method of synchronizing may include accounting for the mismatch between the asynchronous clock domains by employing logic in a block.
