FPGA Design: Implementing UART Serial Communication with SystemVerilog

Serial communication is a cornerstone of hardware design, and mastering UART is the perfect gateway to custom digital system design. This text-based guide takes you from basic digital logic concepts to a fully functional serial controller on an FPGA. You will transition from understanding theoretical clock domains to writing clean, synthesizable SystemVerilog code. By studying structured written explanations and modular code snippets, you will gain the confidence to design, simulate, and debug custom hardware interfaces. What you'll learn: - Understand the foundational concepts of asynchronous serial communication, baud rates, and clock division. - Write synthesizable SystemVerilog code for both UART transmitter and receiver modules. - Apply metastability mitigation techniques using synchronizers for reliable external data sampling. - Design robust finite state machines to control data transmission flow and detect start/stop bits. - Create testbenches to simulate and verify your digital designs using modern validation practices. The course starts with essential terminology and the mechanics of UART protocols before guiding you step-by-step through module architecture, signal synchronization, and simulation verification. It is designed for aspiring hardware engineers and digital design hobbyists new to FPGA development, with no prior hardware description experience required.
