3.2.1. Module Definition

Try these first

1. 1.

   What is a Verilog module?

   Hint

   Consider how software functions work.

2. 2.

   What do inputs in a module represent?

   Hint

   Think about directions of signal flow.

3. 3.

   What does a Verilog module encapsulate?

   • Functionality
   • Data Types
   • Signals

   Hint

   Think about what a module represents.

4. 4.

   True or False: A wire in Verilog can store a value.

   • True
   • False

   Hint

   Consider the role of wires in a circuit.

5. 5.

   Design a Verilog module that implements a 4-to-1 multiplexer. Include ports for selecting inputs and outputs.

   Hint

   Think about how a multiplexer routes different input signals to one output.

6. 6.

   Explain how using hierarchical module design can benefit simulation and debugging.

   Hint

   Consider the implications of modular code like in software design.
