FPGA Metastability Solutions
Gisselquist Technology recently posted a good blog article about metastability and common solutions. If you are trying to learn FPGAs, you’ll want to read it. If you know a lot about FPGAs already, you might still pick up some interesting tidbits in the post.
Don’t let the word metastability scare you. It is just a fancy way of saying that a flip flop can go crazy if the inputs are not stable for a certain amount of time before the clock edge and remain stable for a certain amount of time after the clock edge. These times are the setup …read more
