Is Your Synchronizer Doing its Job (Part 1)?

Is Your Synchronizer Doing its Job (Part 1)?
by Jerry Cox on 06-18-2013 at 8:30 pm

Recently, I discussed the increasing risk of metastability hazards at nanoscale geometries. These risks are significantly aggravated at low supply voltages and low temperatures and must be addressed during the design cycle of any mission critical application. This time I discuss what it takes to estimate a synchronizer’s … Read More


Metastability and Fatal System Errors

Metastability and Fatal System Errors
by Daniel Nenni on 06-09-2013 at 3:00 pm

Metastability is an inescapable phenomenon in digital electronic systems. This phenomenon has been known to cause fatal system errors for half a century. Over the years, designers have used convenient rules of thumb for designing synchronizers to mitigate it. However, as digital circuits have become more complex, smaller … Read More
