Lab 4: Introduction to FPGA Design
Objective:
New Design
Your boss has been working on a new logic circuit and would like you to do some prototyping work. He
has reduced the design to two functions (s and co) of the same input variables (ci, x, y).
s(ci, x, y) = m(1,2,4,7) and co(ci, x, y) = m(3,5,6,7)
For your design use the following input/output assignments.
CO:
S:
CI:
A
B
LD7
LD6
SW2
SW1
SW0
Also, reflect the current state of the switches (SW2, SW1, SW0) on LED’s (LD2, LD1, LD0)
respectively.
1. Design, simulate, build (on FPGA), and verify the logic.
