Shankar Sastry Hybrid system model of Newton’s Cradle, built using HyVisual. Mission The goal of the Center is to provide an environment for graduate research on the design issues necessary for supporting next-generation embedded software systems. The research focus is on developing modelbased and tool-supported design methodologies for real-time fault-tolerant software on heterogeneous distributed platforms. CHESS provides industry with innovative software methods, design methodology and tools while helping industry solve real-world problems. CHESS is defining new areas of curricula in engineering and computer science which will result in solving societal issues surrounding aerospace, automotive, consumer electronics and medical devices. The Problem: intensive use of embedded software in complex physical systems, such as cars. Affiliated faculty CHESS Software Examples of CHESS software include: • HyVisual, a block-diagram editor and simulator for continuous-time and hybrid systems (shown at the left) • CHIC, a modular verifier for behavioral compatibility of software and hardware component interfaces. • Metropolis, a design environment for heterogeneous systems • MetroII, enhancements to Metropolis: heterogeneous IP import, orthogonalization of performance from behavior The research laboratory: software frameworks and test systems such as the Toyota test cell for engine control technology. Janos Sztipanovits, Vanderbilt, ECE Gautam Biswas, Vanderbilt, Computer Science Bela Bollobas, University of Memphis, Mathematics Gabor Karsai, Vanderbilt, ECE Jonathan Sprinkle, University of Arizona, ECE The research laboratory: software frameworks and test systems such as the Berkeley Aerobot Team (BEAR) helicopters. Software engineering today is based on principles that abstract away key semantic properties embedded systems, such as time. The result is ad-hoc architectures and brittle systems. Embedded software architecture tomorrow will be built on sound principles that reflect the interaction of the software with the physical world.
