CDC Verification for FPGA – Beyond the Basics

CDC Verification for FPGA – Beyond the Basics
by Bernard Murphy on 05-23-2017 at 12:00 pm

FPGAs have become a lot more capable and a lot more powerful, more closely resembling SoCs than the glue-logic we once considered them to be. Look at any big FPGA – a Xilinx Zynq, an Intel/Altera Arria or a Microsemi SmartFusion; these devices are full-blown SoCs, functionally different from an ASIC SoC only in that some of the device… Read More

Is Your Synchronizer Doing its Job (Part 2)?

In Part 1 of this topic I discussed what it takes to estimate the mean time between failures (MTBF) of a single stage synchronizer. Because supply voltages are decreasing and transistor thresholds have been pushed up to minimize leakage, the shortened MTBF of many synchronizer circuits at nanoscale process nodes is presenting… Read More
