Question 1

What is the primary characteristic of a combinational circuit?

  • It has memory
  • It outputs based on current inputs
  • It cannot perform arithmetic

💡 Hint: Think about whether the circuit remembers inputs.

Question 2

True or False: Sequential circuits can be designed without using flip-flops.

  • True
  • False

💡 Hint: Consider if there are states involved.

Challenge Problems

Push your limits with challenges.

Question 1

Design a VHDL module for a binary counter that counts up from 0 to 15 and resets to 0 on reset. Explain your design and include a sample code snippet.

💡 Hint: Consider how the counting mechanism works and what additional signals you may need.

Question 2

Create a finite state machine in Verilog for a simple turnstile that only allows one person to enter at a time. Discuss the states and transitions.

💡 Hint: Focus on what conditions lead to transitions and how states affect the output.
