Week 5 HW

Noah Smith

1. In Section 1, don't look at the logic equations provided to you. From the state table, find the logic equations for q1(n+1) and y and draw the sequential circuit for q1(n+1) and y. (10 points)

2. Repeat the work in Section 3. Use two methods, the given one and the behavioral one. Show simulation results. (15 points)

Code and results for the logic expression method.

Code and results for the behavioural method.

3. Similar to the sequence detector in Section 3, change the sequence to be detected to 1011, design the state diagram, draw the truth table, find the logic equations, and design the verilog module and testbench to verify the logic. (15 points)

Here is the hand work for the sequence detector for 1011.

Code for the sequence detector of 1011, I chose to use the behavioral method to do this as it was easier to troubleshoot than the logic equations. This behavioral method was built directly off the state diagram.

Simulation results of the sequence detector.

4. Simulate the four types of shift registers in Section 5. (20 points)

Serial in Serial out code and simulation.

Serial in Parallel out code and simulation.

Parallel in serial out code and simulation

Parallel in parallel out code and simulation.

5. Build a counter module and show the simulation results. (20 points)

I chose to implement the up down 4 bit counter with reset functions. Code and simulation below

6. Find the logic equation of the following circuit and implement it in verilog. Show the simulation results. (20 points)
