This project includes several examples of Pluscal/TLA+ modeling of distributed systems/protocols. Also see https://github.com/muratdem/HLC for Hybrid Clocks modeling.
For more examples and reading on Pluscal/TLA+, [you can check my blog] (http://muratbuffalo.blogspot.com)
[This directs you to the blog posts about Pluscal/TLA+.] (http://muratbuffalo.blogspot.com/search/label/tla)
To run these Pluscal/TLA+ models, you need the TLA+ toolkit, available at http://research.microsoft.com/en-us/um/people/lamport/tla/tools.html
