An integrated design environment for the automated design of DSP systems is described. The overall design time of complex DSP systems on silicon can be reduced drastically by offering the designer a complete silicon compilation environment, integrating architectural level synthesis tools, a module generator and a floorplanner. The system is supported by a flexible and powerful library. A true exploration of the design space in an interactive way is possible. Examples of the first complex chips that have been designed with this system are discussed.
