Overview

Randomized trial evaluates signal integrity in high-speed multilayer PCBs, indicating significant computational efficiency gains.

Key Points

  • The aim is to develop an efficient method for signal integrity analysis in large-scale multilayer PCBs using spectral clustering techniques.
  • Developed a physics-based broadband analytical model for vias and striplines.
  • Constructed a weighted adjacency matrix for PCB coupling topology.
  • Implemented an adaptive spectral clustering algorithm for automatic region division.
  • Achieved 96% reduction in computational time for signal integrity analysis.
  • Demonstrated good agreement with full-wave simulation across a 42-layer PCB in the 0–40 GHz frequency band.
  • Provided an effective approach for analyzing signal integrity in complex PCB systems.
