To learn and practice schematic entry and simulation.
Problem: Implement an ALU (Arithmetic Logic Unit) satisfying the following functional requirements. You should complete schematic capture tutorial, before you start on this lab.
Function
Select (S) S1 S0
Y
Invert
0 0
A
Add
0 1
A + B
Subtract
1 0
A - B
Double
1 1
2*A

1. Design and create a schematic of the ALU using ISE Schematic Entry tool.
2. Create a test bench and use it to test the ALU functionality. Include at least two test vectors per function.
Deliverables: A concise report that includes your design and simulation results.
Report Organization (A template will be provided on Blackboard):
□ Cover sheet
□ ALU schematic
□ Brief description of your design
□ Simulation waveforms
□ IP Block
□ Feedback: Hours spent, Exercise difficulty (Easy, Medium, Hard)
Important:
□ Do not discard your design. It will be used as starting point for subsequent lab exercise(s).
