Logisim Evolution (1 mark)

This year, you will be working with 3 main environments in CPSC 121 Lab. 1. Logisim Evolution - An open source circuit simulation program. 2. The Magic Box - A basic electronics IC kit provided in-lab. 3. Magic Box Simulator - A simulation of the Magic Box inside Logisim. TODO 1: Download and install logisim. 1. Download and install the appropriate version of Logisim v3.7.2 from github here1 . • logisim-evolution-X.X.X.msi for Windows • logisim-evolution-X.X.X.dmg for Mac • logisim-evolution-X.X.X.rpm/.deb/.jar for Linux • For Windows: ś You might get a pop-up asking you to either Keep or Discard this őle.

ś The őrst time you attempt to run Logisim, you may get a pop-up with the following message: Logisim cannot be opened because it is from an unidentiőed developer. ś If this appears, open Settings and navigate to Security and Privacy. Then, inside the Security and Privacy menu, click on the General tab at the top of the page. ś In the General tab, near the bottom, you should see a message: Logisim was blocked from use because it is not from an identiőed developer. Click on Run Anyway next to this message. ś A pop-up box will appear, click Open and Logisim should open. 2. Open Logisim, which is the circuit simulator we will be using in this class. 3. Go to the File menu and select Preferences 4. Then, go to Layout and make sure Use anti aliasing is un-checked. Close the Preferences window. 5. Click on the Help menu and select Tutorial 6. You will now get a screen with the tutorial. It begins like this:

7. Follow and complete Steps 0 to 4 of the Logisim Tutorial. By the end, you will have completed an XOR circuit. Good work! TODO 2: Export your completed circuit and keep it by going to File->Export Image, you will upload this to Gradescope along with the next step of the Prelab. Be sure you are mostly comfortable with where components are in Logisim. You can zoom in and out in Logisim by changing the percentage zoom at the bottom left.

Overleaf Registration (1 mark)

The pre-lab is due at 9 am on Gradescope on the day of your lab. You should have been registered by us. To login go to https://gradescope.ca (NOT gradescope.com. 1. Register with Overleaf here2 . You can use any email you like. 2. Once you have registered, go in and copy the template here3 by clicking the menu button on the upper left corner. 3. TODO 3: Answer the questions in the project you have copied. Add the screenshot from the Logisim tutorial to the end of this document. • We expect you to learn LaTeX in your own time. Even though it is not required to use LaTeX on Overleaf for the assignments, we strongly recommend you use LaTeX. It makes it much easier to mark assignments/labs and it will become mandatory for some of the upper year Computer Science Courses. • To add the screenshot, search for the łinclude graphicsž command for LaTex on the internet. This should give you a place to start in understanding LaTex. 4. Recompile your document. (You can set Overleaf to do that automatically if you prefer). 5. Export as a PDF document. 6. Login to https://gradescope.ca and TODO 4: Submit the PDF document you have exported from Overleaf. 2 3
