characterization of synchronizerscharacterization of synchronizers and metastabilityand 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.
