# Eclipse LSAT™

version v0.3-M1

Eclipse Logistics Specification and Analysis Tool (Eclipse LSAT™) is a performance workbench for the rapid design-space exploration of supervisory controllers that orchestrate the behavior of flexible manufacturing systems. Eclipse LSAT™ provides an integrated development environment for the lightweight modeling of the system resources, the system behavior and the timing characteristics. The tool provides various visualizations to explore the controlled system behavior and analysis and optimization techniques to improve the overall system performance.

| The Eclipse LSAT™ project is currently in the Incubation Phase.

## Functionality

Eclipse LSAT™ provides the following functionality to design high-level supervisory controllers.

Modeling

A domain-specific language to model the system and the supervisory controller.

The uncontrolled system is specified in terms of resources, peripherals, actions, motion profiles, and high-level activities. The supervisory controller is specified as a network of finite-state automata, or as sequences of activities that should be (repeatedly) executed.

Eclipse LSAT™ provides design-time feedback to the user and validates that the specification is consistent.

Analysis

Eclipse LSAT™ provides means to analyze the productivity characteristics of the system including makespan, throughput, and latency. Furthermore, it can analyze the critical path and highlight bottlenecks in the system. These analysis techniques can be used to perform a design-space exploration to improve the supervisory controller design.

Visualization

The productivity of the system is shown graphically using Gantt charts. The system specification can also be done using graphical editors for the motion profiles and activity specifications.

Validation

Using conformance checking, the implementation can be validated against the specification.

## Downloads

Eclipse LSAT™ is available as a portable IDE and also as a feature for the Eclipse IDE through the P2 update site repository.

| Can’t wait for the next release? A nightly build of this page is also available, it is built from the develop branch. Please note that APIs, syntaxes and/or functionality might not be stable for nightly builds.

IDE

The Eclipse LSAT™ IDE offers the most complete and integrated experience, from convenient editing to execution of the various tools. It suits most users.

The Eclipse LSAT™ IDE is portable, so just download, extract, and run it, to get started quickly.

Download Eclipse LSAT™ IDE v0.3-M1 (release notes)

Windows

  - Extract the downloaded archive somewhere on your hard disk:

    - Extract to a directory where you have read and write access.

    - There is no need to extract to an empty folder, as all files in the archive are contained within a root folder.

    - Don’t extract in too deep a path as then you may get issues with too long paths.

  - Execute `lsat.exe` from the directory that contains the extracted files to launch the Eclipse LSAT™ IDE.

Linux

  - Extract the downloaded archive somewhere on your hard disk:

    - Extract to a directory where you have read and write access.

    - There is no need to extract to an empty folder, as all files in the archive are contained within a root folder.

  - Execute `lsat` from the directory that contains the extracted files to launch the Eclipse LSAT™ IDE.

P2 update site

The Eclipse LSAT™ P2 update site contains all plugins and features, for easy integration into OSGi-based applications.

Eclipse LSAT™ v0.3-M1 is available as an Eclipse P2 update site:
