Exploiting Communalities In CoDesign

| Basic arguments are described to create a uniied CoDesign environment. A unique feature is the use of a single language to describe systems. Diierent subsets describe hardware as well a software, both structure and behavior. It vividly shows software and hardware are much more alike than usually perceived. Borders between diier-ent descriptions now become artiicial, meaning we can walk much more freely in the design space. Also our tools beneet from the uniication, we need fewer of them and they are inherently more general. Recent developments in functional languages, integrating functional and imperative languages, made this approach practical for the rst time. The tool we are developing is intended to stimulate the integration of software and hardware design tools into genuine CoDesign tools. The use of a modern typed functional language such as Haskell also makes the language into a broad spectrum CoDe-sign language. Keywords| codesign, design re-use, functional imperative programming.
