The behavioural modelling strategy based on state variables and PWL approximations allows us to
represent several chaotic systems at the electronic system level (ESL) of abstraction. The design space
exploration derived from numerical simulation approaches in the time domain can be adopted to estimate the
performance values of the chaotic systems. That is only one part of a design strategy. Indeed, a question remains:
which architecture and parameters values must be selected during the refinement operation of the behavioural
models? Therefore, the synthesis methodology presented in this chapter completes the opamps based-synthesis of
saturated functions introduced in Chap. 4. First, the steps of a new synthesis methodology proposed in this book
for the design of chaotic systems based on behavioural modelling are summarized. The new methodology of
circuit synthesis is performed by three hierarchical levels. Finally, numerical results are confirmed by H-SPICE
simulations to show the usefulness of the proposed synthesis approach.
