Allegro PCB SI – All tiers
  • SigXp User Interface Overhaul
    • Next generation Signal Explorer (SigXp) brings pre-route exploration to every engineer’s desktop
    • PCB layer stackup aware for early tradeoff studies
    • Context sensitive right-mouse-button
    • Never more than a few mouse clicks away from a waveform
    • Improved support for IO Modeling Standards
      • IBIS libraries and models remain in native format
        • Assign, view, or edit models in IBIS format
        • Current DML flow remains as an alternative
    • New wizard imports HSpice models
      • Manual model wrapping no longer required
      • Models can be managed in definable search paths
Allegro PCB SI XL and GXL
  • Full Wave field solver now supports surface roughness
    • Three modeling techniques to choose from: Hammerstad, Modified Hammerstad, or Exponential model
Allegro PCB SI GXL
  • Signal Quality Screening of routed signals streamlines Channel Analysis flow
    • Signal quality screening reduces verification cycle
      • Ability to screen channels for candidates to perform detailed analysis
      • Results based on signal-to-noise ratio of impulse response
      • Enables more design cycles to improve design performance
