This work addresses the research and development of an innovative optimization kernel applied to analog integrated circuit (IC) design. Particularly this works describes the modifications inside the AIDA Framework an electronic design automation framework fully developed by at the Integrated Circuits Group-LX of the Instituto de Telecomunicações Lisbon. It focusses on AIDA-CMK by enhancing AIDA-C which is the circuit optimizer component of AIDA with a new multi-objective multi-constraint optimization module that constructs a base for multiple algorithm implementations. The proposed solution implements three approaches to multi-objective multi-constraint optimization namely an evolutionary approach with NSGAII a swarm intelligence approach with MOPSO and stochastic hill climbing approach with MOSA. Moreover the implemented structure allows the easy hybridization between kernels transforming the previous simple NSGAII optimization module into a more evolved and versatile module supporting multiple single and multi-kernel algorithms. The three multi-objective optimization approaches were validated with CEC2009 benchmarks to constrained multi-objective optimization and tested with real analog IC design problems. The achieved results were compared in terms of performance using statistical results obtained from multiple independent runs. Finally some hybrid approaches were also experimented giving a foretaste to a wide range of opportunities to explore in future work.
