DESIGNING AND VERIFICATION OF ASYNCHRONOUS FIFO

Piyush Kumar, Prof. Rahul Moud

Abstract


Asynchronous FIFOs are often used to safely pass data from one clock domain to another asynchronous clock domain. Using a AFIFO to pass data from one clock domain to another clock domain requires multi -asynchronous clock design techniques. There are many ways to design a FIFO but still make it difficult to properly simulate and analyse the design.

FIFO can be either synchronous or asynchronous. The basic difference between them is that the entire operation of synchronous FIFO is dependent on the single clock whereas asynchronous FIFO have separate clock for the write operation and read operation.

This paper discusses about Asynchronous FIFO design and verification using Verilog and analyse the outputs using simulation performed in Questasim
