Power Integrity and EMI

FAST EMC VERIFICATION

  • Fast EMC noise source identification with what-if capabilities.
  • Complete board EMC screening, worst case EM emission prediction.
  • Based on industry-accepted R&D approach (UMR EMC Expert System Consortium).
  • Fast algorithms to analyze: Differential Mode Radiation (DM), Common Mode Radiation (CM), and Power Bus Noise (PB).
  • Display heatmap style EMI estimation results directly on eCADSTAR PCB Editor canvas.


POWER INTEGRITY – DC ANALYSIS

  • Numerical frequency-domain solver (2.5D approach) for DC and IR-Drop analysis with user-controlled meshing density.
  • Allows analysis of arbitrary/irregular PWR/GND shapes.
  • DC voltages, IR-Drop, and Current Density.
  • DC SIMULATION – IC POWER-PIN VOLTAGE AND PDS VIA CURRENTS
  • Computation of the max current and the voltage drops of the PDN via’s.
  • Identify problematic vias, define thresholds for the maximum current flow allowed.
  • Parametric studies on PDN vias for what-if analyses.
  • Integration and cross-probing into eCADSTAR main canvas (2D/3D) pinpoints to critical board areas.
  • Calculation of the DC resistance (DC-R analysis) allows verification of IC manufacturer specifications.


POWER INTEGRITY – AC ANALYSIS

  • Numerical power integrity solver for AC analysis.
  • Frequency Domain Target Impedance Analysis (FDTIM).
  • Decoupling analysis.
  • Parametric studies to optimize board decoupling.
  • Add virtual decoupling capacitors at user-defined board positions.
  • Impedance distribution display for user-selected frequencies (heatmap style display on PCB Editor canvas).
  • Cross probe result diagrams and pin-locations between PI/EMI Analysis tool and PCB Editor.

 

"eCADSTAR’s PI Simulations give you confidence in your power delivery design and reduce cost by minimising necessary capacitors. The EMI Analysis module allows you to pre-empt Electro-Magnetic Compatibility issues before compliance testing."
