LAB RULES

Students must strictly adhere to the following rules when using the laboratory for this course; otherwise there would be grade penalties.

• No eating or drinking is allowed in the lab.

• Each Lab board is associated with a number. Once you finished your work, you must place back the board in an orderly manner.

• When you are done, return IC parts into the IC boxes, where you have taken them first.

• Do not unplug any cables (ethernet, monitor, etc.).

• Return all your processes to their first state before you leave the laboratory.

GenAI Policy

Using AI models for coursework including assignments, lab work, projects, exams and quizzes is completely prohibited.

COURSE DESCRIPTION

An introductory course in digital design, covering combinational and sequential circuits, memory and logic arrays and introduction to processor architecture, with a weekly lab. The SystemVerilog hardware description language is used throughout the semester to model and implement digital designs. Credits: 4 units

COURSE CONTENTS

Number systems, Binary numbers, Logic levels, transistors, gates, Boolean expressions. Combinational logic: Boolean algebra, simplification of Boolean expressions. Logic minimization with Karnaugh maps, don't-care conditions. Introduction to SystemVerilog. Combinational building blocks, multiplexers, decoders, propagation delays. SystemVerilog modeling. Sequential logic: SR latch, D-latch, D flip-flop, synchronous sequential circuits. Finite State Machine (FSM) design, Moore and Mealy models, state encodings, timing of sequential circuits. SystemVerilog modeling of sequential circuits. Signed numbers, Adders, ALU, comparators. Registers, register files. Counters, timers. High level state machines (HLSM), RTL design, RAM, ROM. FPGA, introduction to general purpose processor architecture.

• Frank Vahid, Digital Design with RTL Design, VHDL and Verilog, 2nd ed. John Wiley, 2011. (Recommended)
  

Important Note:

Only original and unmarked textbooks will be allowed in the midterm/final exam. If you have any notes/drawings/markings/etc. on your textbook, you will not be able to use it during the midterm/final exam.

GRADING

• Labs: 15 %
  

• Project: 10 % (Report: 10%, Submission/Demo: 90%)
  

• Quizzes: 15 % (possibly 3 quizzes with/without prior notice)
  

• Midterm Exam: 30%
  

• Final Exam: 30%
  
  

FZ POLICY

Students who fail to meet the following requirements will receive an FZ grade:

• Weighted average score of the midterm exam and quizzes (2*midterm-score + avg-quiz-score) /3: at least 40%.
  

• Average score of the labs and project (avg-lab-score + project-score)/2: at least 50%.
  

• Absent from no more than 1 Lab.
  

Only the grades until the FZ deadline will be considered while computing the average scores above. Students who receive FZ cannot attend the final exam.

Late submissions policy

We follow no extension policy.
