3. Verilog-Based RTL Design

Try these first

1. 1.

   Define what a module is in Verilog.

   Hint

   Think of it as a building block.

2. 2.

   What is the primary purpose of a testbench?

   Hint

   Consider what you would use to check if your design works as intended.

3. 3.

   What is the primary role of Verilog in digital design?

   • A. To create analog circuits
   • B. To model digital systems
   • C. To write software programs

   Hint

   Think about the type of systems Verilog is used to describe.

4. 4.

   True or False: The reg data type in Verilog can hold values.

   • True
   • False

   Hint

   Consider the difference between `reg` and `wire`.

5. 5.

   Design a 4-bit binary up-counter in Verilog and create a state transition diagram.

   Hint

   Visualize how the state flows from 0 to 15, then wraps around.

6. 6.

   Write a testbench for your up-counter. Include checks for counting correctness and reset functionality.

   Hint

   Think about how you would verify the counter's behavior across multiple clock cycles.
