The Clock-Domain-Crossing Conundrum

– Jerry Cox The Clock-Domain-Crossing conundrum is this:  Where is the evidence of Clock-Domain-Crossing (CDC) failures that have occurred during a product’s service life? We know there have been products that have had CDC failures during test and been re-spun,...

Synchronization and Metastability

Steve Golson Trilobyte Systems ABSTRACT The phenomenon of metastability is inherent in clocked digital logic. Many techniques have been presented for minimizing metastability, both for crossing clock domains, and for handling asynchronous inputs. Some of these “best...

Ambiguous Behavior of Logic Bistable Systems

Marco Hurtado and David Elliott Washington University, St. Louis First presented at Allerton Conference, October 1-4, 1975 ABSTRACT The standard specifications of logic bistable devices do not specify the behavior under conditions in which the input is logically...

Simulating the Behavior of Synchronizers

J. Cox, T. Chaney, D. Zar 13 Feb 2011 By simulating the behavior of a synchronizer, an estimate of its Mean-Time-Between-Failures (MTBF) can be obtained. The method for estimating MTBF described here was originally based on the work of Molnar and Rosenberger [1], work...

A Public Synchronizer

GET THE PUBLIC SYNCHRONIZER NOW You might ask yourself “Why would anyone want to have a public synchronizer available to download?” Usually designers just grab a flip-flop from his or her company’s or a standard cell vendor’s library. However, are these handy...
