Seven-Segment Display on an FPGA

Introduction:
In this lab we use Verilog to create code that we will use in vivado to make our FPGA board function

Materials and Methods:
gvim(was used to write the verilog), Vivado and Basys 3Board

Results:

Task 1: Using Verilog and Vivado simulate in vivado and on the board, 1. Inverter, 2. 2-bitFull Adder, 3. 8-Input And, 4. 4-1 MUX

Task 2: Using Verilog and Vivado design a Running LED Program on the FPGA Board.

5. Discussion
This Lab assignment was good to complete because it allowed me to complete more complex simulations on both Vivado and on the Basys 3 Board. Overall I was able to successfully complete the lab even though I had a difficult time getting the 2-bit Full Adder to both simulate and operate on the Basys 3 board correctly.
