Good list. I've seen use of both synchronous and asynchronous resets. People have some good arguments for both methods sort of like the tabs vs spaces arguments

- gluggymug 9y agoThe problem is that reset logic requires a bit of design rather than hard fast rules. Designs are getting larger these days with a lot of 3rd party IP that you can't assume use a particular reset method. Tips #2 and #5 in this article, http://www.eetimes.com/document.asp?doc_id=1278998 http://www.eetimes.com/document.asp?doc_id=1278998 , explain how you have to tailor your reset methods to the modules you are integrating. If you don't, you chew up resources. A new FPGA designer should learn the first principles so they can understand how to make decisions and where to look for potential issues when bugs occur.
