"A cyber-physical system (CPS) integrates computing and communication capabilities with monitoring and / or control of entities in the physical world dependably, safely, securely, efficiently and in real-time." - S. Shankar Sastry
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 model-based 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.

Hybrid system model of Newton’s Cradle, built using HyVisual.
The Problem: High speed printing presses require millisecond timing over 100 meters
The Problem: intensive use of embedded software in complex physical systems, such as cars.
The research laboratory: software frameworks and test systems such as the Toyota test cell for engine control technology.
The Problem: intensive use of embedded software in complex physical systems, such as aircraft.
The research laboratory: PTIDES: Programming Temporally Integrated Distributed Embedded Systems
The PTIDES project focuses on model-based design principles for event-triggered real-time distributed systems.
The research laboratory: software frameworks and test systems such as the
Aircraft (Prof. Tomlin)
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.
This work was supported in part by the Center for Hybrid and Embedded Software Systems (CHESS) at UC Berkeley, which receives support from the National Science Foundation (NSF awards #0720882 (CSR-EHS: PRET), #0931843 (CPS: Large: ActionWebs), and #1035672 (CPS: Medium: Ptides)), the Naval Research Laboratory (NRL #NOOI73-12-1-G015), and the following companies: Bosch, National Instruments, and Toyota.
The Solution: PTIDES is used to generate code for different microcontrollers.
Embedded software architecture tomorrow will be built on sound principles that reflect the interaction of the software with the physical world.
