The Ptolemy project is an ongoing project to studying the modeling, simulation, and design of concurrent, real-time, embedded systems. The focus of the Ptolemy project is on the assembly of concurrent components. The principal product of the project is the Ptolemy II model-based design and simulation tool. The Ptolemy project is conducted in the Center for Hybrid and Embedded Software Systems (CHESS) in the Department of Electrical Engineering and Computer Sciences of the University of California at Berkeley, and is directed by Prof. Edward Lee.

The key underlying principle in the project is the use of well-defined models of computation that govern the interaction between components. A major problem area being addressed is the use of heterogeneous mixtures of models of computation.

The project is named after Claudius Ptolemaeus, the second century Greek astronomer, mathematician, and geographer. Claudius Ptolemaeus (Greek: ; c. ...
