Design for specific customer service plays a crucial role for the majority of the market in modern electronics. However, adaptability to an individual customer results in increasing design costs. A key to manage these opposite requirements is a wide application of computer aided design tools for multi-objective optimisation of existing IP blocks. In this paper we introduce a new approach to multi-objective optimisation of mixed analoguedigital signal circuits on the base of the univariate marginal distribution algorithm. Practical illustration of the use of this approach is demonstrated for an industrial electronics application design. Experiments indicate that multi-objective optimisation of mixed analogue-digital signal circuits on the base of the univariate marginal distribution algorithm meets different design specifications.
