Characterization presentation Winter Performed by: Tomer Michaeli Liav Cohen Supervisor: Shlomo Beer Gingold In collaboration with: characterization of synchronizers and metastability and metastability

Motivation In modern systems, there are several domains with different frequencies. To communicate between them synchronization is needed. Synchronization is achieved by means of a synchronizer’. Designing and building synchronizers is one of the main priorities of the most leading companies in the world because efficient synchronization system will enable significant power saving.

Project subject Manual measurements of synchronization Circuits and comparison to results on chip. Use the word direct instead of Manual Direct measurments

Project goals Learn the direct measurement method. Building and improving of a measurement system for synchronization to characterize performance of synchronizers.
