Lab Handout

Special homework (digital logic design review) Due Tuesday, Jan. 15

Lab #0 Tutorial - (1/14-16) Introduction to lab hardware & software

Nexys4 Master Constraints File

Lab #1 - (1/22-23) Combinational Logic Design Using Logic Equations

- VHDL model template file for Lab 1

Lab #2 - (1/28-30) Sequential Logic Design Using Logic Equations

- VHDL model template file for Lab 2

Lab #3 - (2/4-6) Combinational Logic Design Using a Behavioral Model

- Viewing and editing implemented designs in Vivado

Lab #4 - (2/11-13) Sequential Logic Design Using a Behavioral Model

- Post-Implementation Timing Simulation

Lab #5 - (2/18-20) Parameterized VHDL Universal Register/Counter

· VHDL debounce.vhd circuit model

Lab #6 - (2/25-27) Parameterized VHDL Register File Design with Test Bench

Lab #7 - (3/4-6) Hierarchical VHDL Modeling of Manually Controlled Display System

Lab #8 – (3/18-20) “Design your own lab project” You are to

1. Identify a problem: Come up with an idea for a system design to be implemented on the Nexys4 DDR board that will perform some “application”.

2. Formulate the problem: Write a set of requirements for the proposed system.

Email your proposed project identification and formulation to Prof. Nelson during the week before Spring break, so that feedback can be provided on the appropriateness of the project as a one-lab session project.

3. Solve the problem: Design, implement, verify, and test the design in lab.

4. Report: The lab report for this project should have at least three sections, corresponding to the headings listed above (identify, formulate, and solve the problem).

Lab #9 - (3/25-27) PicoBlaze Programming, Simulation and Synthesis.

· Links to PicoBlaze User Manual, User Guide, Assembler and Tutorial files provided above.

Lab #10 - (4/1-3) Interfacing external devices to PicoBlaze via input/output ports.

Lab #11 - (4/8-10) Interfacing external devices to PicoBlaze via interrupt-driven operation.

Lab #12 - (4/15-17, 22-24) PicoBlaze-Controlled Display System – Hint: One solution to bleeding and/or dim display problem is to add a 15-bit register at the output (for the 7 segments and 8 enable values) which is enabled by the write strobe (this will hold the 7-segment value plus the corresponding digit enable for the maximum amount of time until the next value is ready for display for good brightness with minimum bleeding).
