CSCI 2121: Computer Organization and

Assembly Language

Lab 5

Design Sequential Circuits in Verilog III

February 27, 2019

1 Learning Objectives

In this lab, you will use what we have learned about sequential circuits to implement different

types of shift registers, a sequence detector, and rising edge detectors.

2 Submission Instruction

Save code for each task as .sv file, with the name specified at the end of each lab task.

Put all lab files into one folder, and compress the folder to a .zip file.

Submit it on Brightspace.

Deadline for submission: Sunday 2nd March, 2019, 11:55 pm.

As the marking will be done automatically by a script, it is important that you follow these

instructions and save your files with correct names and .sv extension.

3 Lab Assignment

3.1 Lab Task 1

Design a 4-bit shift-left register

Implement a 4-bit shift-left register. The skeleton code is available at

https://www.edaplayground.com/x/34QM. Name your file as task1.sv

Figure 1: 4-bit shift-left register

3.2 Lab Task 2

Design a 4-bit shift-left-or-right register

Implement a 4-bit shift-left-or-right register. It performs the work of the shift right register if

the direction is 0, or the shift left register if the direction is 1. The skeleton code is available here

at https://www.edaplayground.com/x/4C3Z. Name your file as task2.sv

3.3 Lab Task 3

Design a 16-bit shift register

Implement a 16-bit shift register using only 4-bit shift-right registers.Complete the circuit and

make sure it passes all tests. The skeleton code is available at https://www.edaplayground.com/x/35JE.

Name your file as task3.sv

3.4 Lab Task 4

Design a sequence detector

Design a finite state machine that has one input line x and one output line z. The input line

receives a stream of bits. The machine outputs a 1 when exactly two of the last three inputs are

1; otherwise, it outputs a zero. An example is shown by Figure 3. The skeleton code is available

at https://www.edaplayground.com/x/3b8Q. Save this file as task4.sv

3.5 Lab Task 5

Design a rising edge detector (Moore machine)
