SI & PI SIMULATIONS

SI Analysis

  • Allegro Package SI is used for Signal net SI analysis.
  • Define Specification & Stack-Up Verification
  • Controlled impedance calculation – Can model diffpair and SE signals separately for loss analysis – Can analyze Xtalk for different spacing. – Can analzse signal speed that can be supported by the trace

PI Analysis

  • Power/GND Impedance profile analysis  De-coupling Capacitors Estimation  Common-mode radiated noise (EMI)  IR drop analysis
