TAPAAL3.9.3

TAPAAL lets users construct formal models of systems whose behavior depends on timing, using Timed-Arc Petri nets. Its modeling functions describe these nets in a structured form suitable for precise analysis. Users can simulate a model to examine how it behaves as time advances. They can also verify formal properties, moving beyond observation to assess whether the model satisfies defined conditions.

By combining modeling, timed simulation, and verification, TAPAAL supports a complete workflow for studying a system’s formal behavior. It is intended for students, instructors, and others working with formal computer-science modeling, particularly when timing must be represented explicitly. Typical uses include educational exercises in which a system is modeled, its execution is explored, and its properties are checked. The software was developed at the Department of Computer Science at Aalborg University in Denmark.

TAPAAL is published by Kenneth Yrke Joergensen, and the current version is 3.9.3. It runs on Linux, requires snapd, and supports the amd64 architecture. Classified as Education, it is distributed as freeware rather than through a paid software license.
