CPU Notifier

• The implementation of the CPU Notifier machine as presented in the Aeroconf 2024 conference.*

Overview

This is a swift package that leverages swiftfsm to define the Logic-Labelled Finite State Machine (LLFSM). This package also provides the ability for swiftfsm to generate a Uppaal model that represents the state-space of the LLFSM.

Prerequisites

Swift 5.9 or Higher

To build, download Swift from https://swift.org/download/ -- if you are using macOS, make sure you have the command line tools installed as well). Test that your compiler works using swift --version, which should give you something like

$ swift --version
swift-driver version: 1.45.2 Apple Swift version 5.9...
Target: x86_64-apple-darwin20.3.0

on macOS, or on Linux you should get something like:

$ swift --version
Swift version 5.9 (swift-5.9-RELEASE)
Target: x86_64-unknown-linux-gnu

Accessing the Pre-Generated Model

We have provided a pre-generated model that you may inspect. Please find it on the Releases page.

Generating the Uppaal Model

Simply run the following to generate the uppaal model:

$ swift test

This should create a folder in your current directory containing 0.xml file which can be opened by Uppaal version 5.0.0.
