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...

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...

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...

Jerry Cox, ScD Two new tools, MetaACE and PublicSync, have been recently introduced by Blendics. Together they are capable of the analysis of many aspects of synchronizer performance. The benchmark circuit, PublicSync, can be simulated by the analysis tool, MetaACE,...

Jerry Cox From the beginning, now some 50 years ago, we often ran into requests for help such as: “we need help, but this work needs to confidential. If this became known, it would damage the reputation of our product.” It was, and is, rare where we were allowed to...

Salomon Beer Abstract— Synchronizers are used to mitigate the effects of metastability in multiple clock domain System-on-Chip devices. In order to enable reliable synchronization, the synchronizer MTBF (Mean Time Between Failures) should be much longer than the...

Jerry Cox Metastability is an inescapable phenomenon in digital electronic systems, particularly those with multiple independent clock domains such as System-on-Chip (SoC) products. This phenomenon has been known to cause fatal system errors for half a century. Over...

Thomas J. Chaney It has now been almost 50 years since my first meeting with the glitch. It WAS a meeting. For me, it didn’t have the power or majesty of a “discovery”. It was more like a meeting. The realization that I had stumbled into a discovery came later....

Jerry Cox 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 which depended heavily for...
