The design and optimisation of analogue and mixed-signal integrated circuits become intractable with technology scaling.It gives rise to multi-dimensional tradeoffs among its numerous performance metrics.Evolutionary algorithms are being explored to generate possible solutions having goodness of fit with the desired solution.In this direction, a novel fitness evaluation function integrated with PSO and PSO-SPICE framework is proposed to design and implement multi-objective optimisation for analogue and mixed-signal circuit design automation.The framework is demonstrated to automatically design and optimise the multi-objectives of 2-stage op-amp and 4-bit flash ADC.The proposed fitness evaluation function demonstrate large design outperformance independent of quality of initial population and requiring no adaptive weights.The novel fitness function driven PSO-SPICE framework exemplifies a robust, scalable, and precise method for multi-objective optimisation of analogue and mixed-signal circuits of varying scale and design complexity.
