HyVisual is a Hybrid System Visual Modeler. Hybrid systems are systems with continuous-time dynamics, discrete events, and discrete mode changes. This visual modeler supports construction of hierarchical hybrid systems. It uses a block-diagram representation of ordinary differential equations (ODEs) to define continuous dynamics. It uses a bubble-and-arc diagram representation of finite state machines to define discrete behavior. HyVisual includes a facility to translate Hybrid System Interchange Format (HSIF) files into MoML, the XML format used to represent Ptolemy II Models. HSIF, was developed by the Institute of Software Integrated Systems (ISIS) at Vanderbilt University as part of the ISIS MoBIES effort. The HSIF documentation states: "The goal of HSIF is to define an interchange format for hybrid system models that can be shared between modeling and analysis tools. HSIF models represent dynamic systems, whose dynamics includes both continuous and discrete behaviors." The HyVisual 2.2-beta is a runtime only release, our plan is to release the source code with the next release of Ptolemy II, due in May. HyVisual is built on top of Ptolemy II, a framework supporting the construction of such domain-specific tools. HyVisual is based on the work of many participants, but following people were instrumental in the creation of HyVisual: Jiu Liu (currently at Xerox Parc) developed the Continuous Time domain while at UC Berkeley and continues to collaborate with the Ptolemy group. Xiaojun Liu developed the Finite State Machine domain and has helped support the the CT domain. Stephen Neuendorffer developed Vergil, the block diagram editor and has help support the domains. Haiyang Zheng developed the HSIF translation capability and has helped support the domains. Professor Edward A. Lee mentored all of us, developed many of the features in Vergil and wrote the HyVisual documentation. My role has been to build and test the release and manage the software development process. -Christopher Christopher Hylands [EMAIL PROTECTED] University of California Programmer/Analyst Chess/Ptolemy/GSRC US Mail: 558 Cory Hall #1770 ph: (510)643-9841 fax:(510)642-2739 Berkeley, CA 94720-1770 home: (510)526-4010, (707)665-0131 (office: 400A Cory) [This message is being sent to the ptolemy-interest and ptolemy-hackers.
