Abstract:
A method and system for eliminating implementation timing with respect to a synchronization circuit. A standard library cell having a pair of clock input pins can be connected with at least two asynchronous clock domains of the synchronization circuit in order to measure a timing signal between the flip-flop latches crossing the asynchronous clock domain. A timing delay with respect to each bit pair of the asynchronous clock domain can be determined utilizing a static analysis approach during a layout phase in order to effectively synchronize the asynchronous clock domain. Each bit pair of the asynchronous clock domain can be checked via a static timing analysis tool in order to thereby improve functional accuracy of the synchronization circuit in a wide range of digital logic designs.
