Required Notions and Knowledge

Example

Make a circuit that turns on LEDG7 with a variable intensity controlled by a value set by the SW7-SW0 switches using a variable duty cycle signal generator based on an 8-bit counter. The numerator will be described as a separate Verilog mode, and will be instantiated in the signal generator.

Exercise

Build a circuit that instantiates 8 variable duty cycle signal generators to form a LEDG7-LEDG0 intensity ramp with the following features:

  • LEDG0 intensity, denoted I LEDG0 is determined by SW7-SW0
  • The LEDG0-7 intensities respect one of the following relationships (the teacher will assign each of the students one of the following relationships):
    1. I LEDG0 < I LEDG1 < I LEDG2 < I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
    2. I LEDG0 > I LEDG1 < I LEDG2 < I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
    3. I LEDG0 > I LEDG1 > I LEDG2 < I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
    4. I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
    5. I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
    6. I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 > I LEDG5 < I LEDG6 < I LEDG7
    7. I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 > I LEDG5 > I LEDG6 < I LEDG7
    8. I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 > I LEDG5 > I LEDG6 > I LEDG7

Bonus Exercise

Build a circuit that then turns off a led gradually, using a variable duty cycle generator.
