Lesson 07: Modeling Digital Circuits in Verilog

Verilog HDL provides different levels of abstraction to describe digital circuits: gate-level, dataflow, and behavioral modeling. Each modeling style serves different purposes and offers varying levels of detail and ease of use.



  • Gate-Level Modeling: Provides detailed hardware representation using basic gates. Best for small designs or when precise control over hardware is needed.
  • Dataflow Modeling: Describes the flow of data using continuous assignments. Suitable for combinational logic and medium-sized designs.
  • Behavioral Modeling: Uses procedural statements to describe complex behavior. Ideal for large and complex designs, particularly with control logic.
