Disclaimer: While you are free to install Alloy and Spin on your personal computers, there may be some "quirks" based on your machine's configuration (especially SPIN on Mac's). I would strongly suggest defaulting to the lab systems for all on-line exams and testing projects and activities. All grading will be done using an SE Lab image. I will create a discussion forum in myCourses for students to share installation advice.
  1. The Alloy community web site is at alloy.mit.edu.
  2. If you want to install Alloy on your own computer:
    1. In the upper pane, click the download link.
    2. Select either alloy4.2.dmg for OS X or alloy4.2.jar for Windows or Linux; in all cases you need at least Java 6 to run the tool.
  3. The documentation link in the upper pane leads to a page with several useful links (we suggest bookmarking this link):
    1. An FAQ about Alloy.
    2. A reference manual
    3. A quick guide to Alloy 4
    4. An on-line tutorial
    5. Slides from a one day tutorial.
Promela / Spin
  1. Our primary source for information on Promela (the PROtocol MEta LAnguage) and SPIN (Simple Promela INterpreter) is the text by Ben-Ari. Gerard Holzman, the creator of the system, has a book that goes deeper in to the underlying theory, but it's more than we need.
  2. A good supplemental source is on the SPIN community website, spinroot.com. This is where you can find downloadable versions of the tools for your own computers. In addition, there are tutorials and a community forum.
  3. To download jSPIN 5.0 for Windows go to Google Code and select jspin-5-0.exe
  4. To download SPIN for Mac go to the SPIN site and follow instructions for Mac installation

    Here are some additional Mac installation tips: jSpin for Mac and Linux

Data Modeling - Entity Relationship Diagrams (ERD)
  1. There are a number of ERD-like drawing tools available. In class, and for your own use I would suggest Lucidchart : https://www.lucidchart.com/. You will need to sign-up (free) with your RIT email address (*.rit.edu) in order to get features beyond the normal trial sign-up Lucidchart offers.
  2. Another  tool to look at is the ERD features in Microsoft Visio. Visio is installed on the SE lab machines and is available through the SE Deptartment's Academic Alliance with Microsoft: http://www.se.rit.edu/content/software-vendor-alliances (Note that Lucidchart is able to import Visio diagrams.)
