Notions and Knowledge Required
- Boolean logic and numbering systems
- Verilog Syntax Verilog_EN
- Using the Altera Quartus II Synthesis Program
- List of pins for DE1 board, List of pins for DE1-SoC board
- Sequential Circuits, Counter
- Pulse generator with variable filling factor
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 fill factor 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 fill factor 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):
- #I LEDG0 < I LEDG1 < I LEDG2 < I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 < I LEDG2 < I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 > I LEDG2 < I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 < I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 < I LEDG5 < I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 > I LEDG5 < I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 > I LEDG5 > I LEDG6 < I LEDG7
- #I LEDG0 > I LEDG1 > I LEDG2 > I LEDG3 > I LEDG4 > I LEDG5 > I LEDG6 > I LEDG7
Bonus Exercise
Make a circuit that then turns off a led gradually, using a variable fill factor generator.
