A First-In-First-Out (FIFO) buffer is a fundamental digital design component that stores data in a queue-like structure. This guide provides a comprehensive explanation of FIFO design principles, depth calculation methods, and a complete SystemVerilog implementation suitable for synthesis.
Finite State Machines (FSMs) are fundamental building blocks in digital design, providing a structured approach to implementing sequential logic. This guide covers synthesizable SystemVerilog FSM design techniques, from basic concepts to advanced implementation strategies.
SystemVerilog provides three special keywords (`unique`, `unique0`, and `priority`) that can be used with `case` and `if` statements to provide synthesis tools with optimization hints and enable runtime checking during simulation.
