Modélisation comportementale des circuits analogiques et mixtes

Abstract : To integrate on one single chip ever more complex systems composed of both digital and analog functions, a hierarchical design methodology is needed. Based on a behavioural modelling of each circuit element, before any architectural choice, such an approach reduces simulation and design times and increases reliability. Successfully applied in the digital domain, this paradigm should now be extended to the analog one. This is now possible due to the recent availability of powerful languages for analog and mixed behavioural modelling. This thesis introduces the usage of such languages in the designer community through the development of a CAD environment providing help for analog and mixed model design. It is based on a functional library dedicated to the modelling of basic circuits (e.g. operational amplifiers) but also of very complex systems such as a security air-bag system. Different description techniques have been studied: SPICE macro-modelling and behavioural modelling with several languages, whose properties have been compared (FAS, C-FAS, HDL-A and MAST). This environment is also composed of an analog characterization tool which is used to rapidly compute model parameters from performance measurements of the associated circuit, through electrical simulations. Moreover, to ease model exchange and transfer libraries into different languages, automatic translators have been developed such as FAS to CFAS, FAS to MAST and FAS to HDL-A.
