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
