Description

Ptolemy is an open-source modeling and simulation software tool that focuses on minimizing the accidental differences in syntax, semantics and pragmatics between different domains of practical systems, such as mechanical systems, electrical systems, and control systems. In this regards, Ptolemy can be used to model the so-called heterogeneous systems that span over multiple domains. The motivation of the project is to utilize Ptolemy to model and simulate complicated optical fiber communication systems that involve continuous-time and discrete-time domains, and possess optical and electrical devices. The system architecture and the data structure in Ptolemy are briefly introduced, with a focus on a class of models named actor- oriented models where “actors” are used to refer to concurrently executed components.

Furthermore, the hierarchical design capability of Ptolemy is illustrated using a simple example. A particularly useful modeling and simulation domain i.e., the synchronous data-flow (SDF) domain is explained, and is used for the set-up and simulation of an example optical fiber communication system. After the explanation of the designed optical fiber communication system components and configuration, we give a live software demonstration of this system using Ptolemy software, to show how components can be added, how simulation can be configured and run, and how simulated signal wave forms and system performance can be visualized.
