2. Introduction
The purpose of this lab was to implement some basic combinational logic both in simulation and on our Basys 3 Board.
3. Results Task 1: This
task asked us to draw a truth table for a two-way stop light and then
simulate that combinational logic both in simulation and on-board.
Figure 1 shows the handdrawn truth table along with a k-map that
would've been used for simlifying if there were more states. Figure 2
shows the simulation implementation of the logic, and Figure 3 shows
the on-board inplementation.

Task 2: This
task asked us to implement a 3-bit even parity generator and a checker
in differen't modules. We used the test bench to attach these two
modules together, and input values for the simulation in Figure 4.
Figure 5 shows the on-board implementation where hardware switches are
used to input values into the parity generator.

4. Discussion This
lab was interesting to code because implementing the logic in
simulation was easy, but transferring that code to the board for me
meant a lot of configuring to get it to work with the hardware. A big
mistake I made during this lab was not checking the diagram on the
website to see that there were actually 7 states instead of 4. So my
K-Map didn't actually simplify anything, and the implementation of the
logic was much more straightforward than it would have been with 7
states. Despite that, it was still a good review of combinational
logic and a good lesson on how to implement it on the Basys 3 Board.
