Improving the Visualization of Alloy Instances
This work addresses visualization limitations for software developers using Alloy to reason about dynamic behavior in early-stage software design, but it is incremental as it builds on an existing tool.
The paper tackled the problem of visualizing behavioral models in Alloy, a formal specification language, by developing a principled approach that improves the Alloy Visualizer's representation of behavior.
Alloy is a lightweight formal specification language, supported by an IDE, which has proven well-suited for reasoning about software design in early development stages. The IDE provides a visualizer that produces graphical representations of analysis results, which is essential for the proper validation of the model. Alloy is a rich language but inherently static, so behavior needs to be explicitly encoded and reasoned about. Even though this is a common scenario, the visualizer presents limitations when dealing with such models. The main contribution of this paper is a principled approach to generate instance visualizations, which improves the current Alloy Visualizer, focusing on the representation of behavior.
