(IMOC-2013), Rio de Janeiro, Brazil, Aug. 2013, pp. 1-4.978-1-4799-1397-8DOI: 10.1109http://hdl.handle.net/11117/2783Highly efficient CAD methodologies based on full-wave EM analysis, for the design of package interconnects are necessary due to the increased frequencies of operation and a desire of faster time-to-market. In this work, we exploit a Broyden-based input space mapping (SM) algorithm with both fine and coarse models implemented with the finite-element method (FEM), to efficiently optimize design parameters of a modern package interconnect. This optimization algorithm has been applied to a single-ended package line resulting in a significant decrease of the return loss in the 5-10 GHz range, requiring just a few fine model evaluations.engSpace MappingPackage InterconnectsEM-based Design OptimizationHigh-speedReturn-lossFEM Space MappingReturn-loss minimization of package interconnects through input space mapping using FEM-based modelsinfo:eu-repo/semantics/conferencePaper
