Simultaneous Multi-Topology Multi-Objective Sizing Across Thousands of Analog Circuit Topologies
This paper presents MOJITO, a system which optimizes across thousands of analog circuit topologies simultaneously, and returns a set of sized topologies that collectively provide a performance tradeoff. MOJITO defines a space of possible topologies as a hierarchically organized combination of trusted analog building blocks. To minimize the setup burden: no topology selection abstract behaviors need to be specified, and performance calculations are SPICE-based. The search algorithm is a novel multi-objective evolutionary algorithm that uses an age-layered population structure to balance exploration vs. exploitation. Results are shown for a space having 3528 one- and two-stage operational amplifier topologies. Categories and Subject Descriptors B.7.2 [Integrated Circuits]: Design Aids General Terms Algorithms, Design Keywords Analog, mixed-signal, integrated circuits, computer-aided design.
