Variation-aware structural synthesis of analog circuits via hierarchical building blocks and structural homotopy

Journal Contribution - Journal Article

This paper presents MOJITO-R, a tool that performs variation-aware structural synthesis of analog circuits. It returns trustworthy topologies by searching across a space of thousands of possible topologies defined by hierarchically organized analog structural building blocks. "Structural homotopy" conducts search at several objective-function tightening levels (numbers of process corners) simultaneously. Multiobjective evolutionary search returns sized topologies which trade off power, area, performances, and yield. An experimental validation run returned 78 643 Pareto-optimal designs, having 982 sized topologies with various specification/yield combinations. A decision tree is extracted to visualize the performance-topology relationship. © 2009 IEEE.
