6. Task 6: Seven-Segment Display (Week 8)

• Objective:

  • Revisit the knowledge points that we have studied.
  • Get to know the operation of a device by reading its manual and/or other material. Specifically in this task, get to know the operation of the seven-segment LED display.
  • Start a design from its block diagram.
  • Model each block, and
  • Model the entire circuit that drives the seven-segment LED display.

6.1. Knowledge Points Revisited

• Hierarchy design and Structure Style Modeling
• Two segment coding style

• Combinational circuit design

  • Decoder:

    • Hex to 7-segment decoder,
    • 3-to-8 decoder

  • Multiplexer

• Sequential circuit design

  • Counter
  • Frequency divider

6.2. New

• Parameterized Design p250-268

  • Generic constant p252-258
  • Array attribute p259-261
  • Unconstrained array p262-267

6.3. Understand the 7-Seg LED Display
