Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Propose a modification to the 4-bit counter so that it counts upwards and resets based on an external signal, not just the clock.

💡 Hint: Consider how you would link this external signal similarly to CLK.

Challenge 2 Hard

Examine the implications of this Verilog code when deployed on an FPGA: How do you verify the counter works as intended?

💡 Hint: Think about creating test vectors for inputs.
