This thesis presents a design approach for digital signal processing integrated circuits. In the first part, we present the different steps of DSP integrated circuit design. Then, we discuss the various methods used at each level and propose a well structured methodology for layout design.

In the second part, the implementation of a tool responding to the requirements issued from part one is discussed. We introduce the object-oriented paradigm used and discuss the expected benefits. The emphasis is there on the application of the theoretical requirements and their mapping into object-oriented structures.
