Mr. Ptolemy Ptolemy II [1][2][3] is a set of Java packages supporting heterogeneous, concurrent modeling, simulation, and design of component-based systems. The emphasis is on a clean, modular software architecture, divided into a set of coherent, comprehensible packages. The kernel package supports definition and manipulation of clustered hierarchical graphs, which are collections of entities and relations between those entities. The actor package extends the kernel so that entities have functionality and can communicate via the relations. The domains extend the actor package by imposing models of computation on the interaction between entities.
Domains that have been created include: The Ptolemy II software architecture supports interaction between domains (heterogeneous modeling). For example, FSM can be combined with CT to model hybrid systems.

Ptolemy II includes a number of support packages, such as
