3. Verilog-Based RTL Design

Verilog is a crucial hardware description language that is essential for modeling and designing digital systems at various abstraction levels. By focusing on the Register Transfer Level (RTL) design, the chapter introduces the essential syntax and constructs of Verilog, emphasizing how engineers can accurately define both the behavior and structure of hardware components. Mastery of Verilog syntax, data types, operators, and procedural constructs equips designers with the necessary skills to create complex digital systems, from simple circuits to advanced ASICs.
