Topology Analysis of Software Dependencies

The investigation of a software system prior to a modification task often constitutes an important fraction of the overall effort associated with the task. Suade is an Eclipse plug-in to automatically generate suggestions for software investigation. The goal of Suade is to increase the efficiency with which developers explore the source code by recommending locations that are likely to be relevant to the task. Based on a context of software elements (fields and methods) explicitly specified by a developer, Suade automatically generates other elements that are likely to be relevant given the context, by analyzing the topology of structural dependencies in a software system.

Generate suggestions by dragging a concern in ConcernMapper (e.g., "Autosave") into the Suade View.


The Suade plug-in depends on
ConcernMapper. To install Suade, please download and install ConcernMapper first.

You can easily install Suade through Eclipse's update mechanism. Suade is distributed under the terms of the Eclipse Public License, v. 1.0

System requirements: Eclipse 3.2, Java 1.4 or later, and ConcernMapper 1.4.0 or later. Suade is currently only tested on Windows.

To install Suade:

  1. From the Eclipse menu bar, select Help | Software Updates | Find and Install...
  2. Select "Search for new features to install" and click Next >
  3. Click on the New Remote Site... button.
  4. For the name, enter "Suade". For the URL, enter "", and click OK
