Asynchronous FIFO Design
Efficient data transfer across asynchronous clock domains
Project Overview
This project focused on designing and verifying an asynchronous First-In-First-Out (FIFO) memory system using Verilog RTL and Cadence Virtuoso. Unlike synchronous FIFOs, an asynchronous FIFO enables data to be written and read across different, asynchronous clock domains, making it an essential component for reliable cross-domain communication in complex digital systems.
