The aim of this unit is to give students a practical introduction to digital logic design and prototyping in FPGAs based on VHDL entry, using industry standard tools. Students will work in a group of 4 to design a functioning digital system and implement it.

Intended learning outcomes

On the successful completion of this project activity students will be able to:

  1. Demonstrate, through practice, the use of VHDL as a modelling language to describe digital logic, including use of common templates to describe combinational and sequential logic blocks;
  2. Explain the hardware implications of a given piece of VHDL code and the limitations imposed in coding for synthesis;
  3. Design combinational and sequential logic blocks and finite-state machines in VHDL based on a given set of functional specifications;
  4. Interpret a specification for a digital system;
  5. Propose modular structural divisions for a complex digital system, and define interfaces for the constituent modules;
  6. Set-up and run simulations and debug VHDL code for correct functionality in the ModelSim simulator, and approach the testing and simulation of a design in a systematic manner;
  7. Use Xilinx to prototype designs in FPGAs;
  8. Prepare and give a group presentation.

Assessment Details

Assignment 1 (30%): An individual take-home exercise that is assessed based on functionality and quality of VHDL code, and analytical and descriptive answers, all related to design of digital circuits and systems. (ILOs 1-6)

Assignment 2(70%): A group exercise that is assessed based on the functionality and quality of submitted code to meet interim specifications (30%) and final specifications (20%). A group presentation describing the design is worth 15%. Finally, 5% of the assessment is based on the performance of the individual as viewed by their group mates and the instructors. (ILOs 1-8)
