characterization of synchronizers and metastability Characterization presentation Winter 2009-10 Performed by: Tomer Michaeli 052792769 Liav Cohen 301242509 Supervisor: Shlomo Beer Gingold In collaboration with:
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 • Learnthe direct measurement method. • Building and improving of a measurement system for synchronization to characterize performance of synchronizers.
