Description
1 Setup
The software you will be using for this assignment and all future circuit based assignments is called CircuitSim.
You can get a copy of CircuitSim from https://ra4king.github.io/CircuitSim/download.
Note that you must have Java 8u152, Java 9, or Java 10 installed for CicuitSim to work probably. If you
have an older version of Java (even Java 8u151), you will encounter several annoying JavaFX bugs. You
have been warned.
2 Assignment
CircuitSim is an interactive circuit simulation package. We will be using this program for the next couple
of homework assignments. Before you start please ensure that you have at least Java 8u152 (JDK) installed
on your computer. This may be a problem if you installed Java during CS 1331 last semester and never
updated. Make sure you update to the latest version of Java 8! CircuitSim will only run on machines with
at least Java 8 installed. Your next homework will involve programming in Java so make sure you have the
JDK installed as well.
CircuitSim is a powerful simulation tool designed for educational use. This gives it the advantage of being
a little more forgiving than some of the more commercial simulators. However, it still requires some time
and effort to be able to use the program efficiently. With this in mind, we present you with the following
assignment:
2.1 Part 1 — Read Resources
Read through the following resources
• CircuitSim Wires Documentation https://ra4king.github.io/CircuitSim/docs/wires/
• Tutorial 1: My First Circuit https://ra4king.github.io/CircuitSim/tutorial/tut-1-beginner
2.2 Part 2 — Complete Tutorial 2
Complete Tutorial 2 https://ra4king.github.io/CircuitSim/tutorial/tut-2-xor
Instead of saving your file as xor.sim, save your file as part1.sim.
2.3 Part 3 — Complete Tutorial 3
Complete Tutorial 3 https://ra4king.github.io/CircuitSim/tutorial/tut-3-tunnels-splitters
Name the subcircuit umbrella, the input in, and the output out. Save your file as part2.sim.
3 Checker
To run the checker, run
$ java -jar hw01-tester.jar
at a command prompt in the same directory as part1.sim and part2.sim. Gradescope uses this same
checker to evaluate your work.

4 Submission
Submit the following files:
• part1.sim
• part2.sim
to Gradescope under the assignment “Homework 01.”
5 Evaluation
Rubric:
• part1.sim — 50%
• part2.sim — 50%
6 Rules and Regulations
6.1 General Rules
1. Starting with the assembly homeworks, any code you write must be meaningfully commented. You
should comment your code in terms of the algorithm you are implementing; we all know what each
line of code does.
2. Although you may ask TAs for clarification, you are ultimately responsible for what you submit. This
means that (in the case of demos) you should come prepared to explain to the TA how any piece of
code you submitted works, even if you copied it from the book or read about it on the internet.
3. Please read the assignment in its entirety before asking questions.
4. Please start assignments early, and ask for help early. Do not email us the night the assignment is due
with questions.
5. If you find any problems with the assignment it would be greatly appreciated if you reported them to
the author (which can be found at the top of the assignment). Announcements will be posted if the
assignment changes.
6.2 Submission Conventions
1. All files you submit for assignments in this course should have your name at the top of the file as
a comment for any source code file, and somewhere in the file, near the top, for other files unless
otherwise noted.
2. When preparing your submission you may either submit the files individually to Canvas or you may
submit an archive (zip or tar.gz only please) of the files (preferred). You can create an archive by right
clicking on files and selecting the appropriate compress option on your system.
3. If you choose to submit an archive please don’t zip up a folder with the files, only submit an archive
of the files we want (see Deliverables).
3
4. Do not submit compiled files, that is .class files for Java code and .o files for C code. Only submit the
files we ask for in the assignment.
5. Do not submit links to files. We will not grade assignments submitted this way as it is easy to change
the files after the submission period ends.
6.3 Submission Guidelines
1. You are responsible for turning in assignments on time. This includes allowing for unforeseen circumstances. If you have an emergency let us know IN ADVANCE of the due time supplying documentation (i.e. note from the dean, doctor’s note, etc). Extensions will only be granted to those who contact
us in advance of the deadline and no extensions will be made after the due date.
2. You are also responsible for ensuring that what you turned in is what you meant to turn in. After
submitting you should be sure to download your submission into a brand new folder and test if it
works. No excuses if you submit the wrong files, what you turn in is what we grade. In addition,
your assignment must be turned in via Canvas. Under no circumstances whatsoever we will accept
any email submission of an assignment. Note: if you were granted an extension you will still turn in
the assignment over Canvas.
3. There is a 6-hour grace period added to all assignments. You may submit your assignment without
penalty up until 11:55PM, or with 25% penalty up until 5:55AM. So what you should take from this is
not to start assignments on the last day and plan to submit right at 11:54AM. You alone are responsible
for submitting your homework before the grace period begins or ends; neither Canvas, nor your flaky
internet are to blame if you are unable to submit because you banked on your computer working
up until 11:54PM. The penalty for submitting during the grace period (25%) or after (no credit) is
non-negotiable.
6.4 Syllabus Excerpt on Academic Misconduct
Academic misconduct is taken very seriously in this class. Quizzes, timed labs and the final examination are
individual work.
Homework assignments are collaborative, In addition many if not all homework assignments will be evaluated
via demo or code review. During this evaluation, you will be expected to be able to explain every aspect of
your submission. Homework assignments will also be examined using computer programs to find evidence
of unauthorized collaboration.
What is unauthorized collaboration? Each individual programming assignment should be coded by you.
You may work with others, but each student should be turning in their own version of the assignment.
Submissions that are essentially identical will receive a zero and will be sent to the Dean of Students’ Office
of Academic Integrity. Submissions that are copies that have been superficially modified to conceal that
they are copies are also considered unauthorized collaboration.
You are expressly forbidden to supply a copy of your homework to another student via electronic means. This includes simply e-mailing it to them so they can look at it. If you supply
an electronic copy of your homework to another student and they are charged with copying,
you will also be charged. This includes storing your code on any site which would allow other
parties to obtain your code such as but not limited to public repositories (Github), pastebin,
etc. If you would like to use version control, use github.gatech.edu
6.5 Is collaboration allowed?
Collaboration is allowed on a high level, meaning that you may discuss design points and concepts relevant
to the homework with your peers, share algorithms and pseudo-code, as well as help each other debug code.
4
What you shouldn’t be doing, however, is pair programming where you collaborate with each other on a
single instance of the code. Furthermore, sending an electronic copy of your homework to another student for
them to look at and figure out what is wrong with their code is not an acceptable way to help them, because
it is frequently the case that the recipient will simply modify the code and submit it as their own. Consider
instead using a screen-sharing collaboration app, such as http://webex.gatech.edu/, to help someone with
debugging if you’re not in the same room.
