EM Prototyping™ – EM Prototyping Before Layout Completion

PeakView® EM Prototyping™ tool addresses the circuit-level EM isolation, coupling and crosstalk simulation at an early stage of the design when the layout is not necessarily LVS-clean. This tool automates the layout preparation of multiple EM devices for combined-layout simulation, modeling and back-annotation while preserving the connectivity throughout the design hierarchy. 

EM Prototyping™ for Coupling and Crosstalk Analysis at Design Floor Plan Stage

  • Full-Wave 3D EM Solver ensures accuracy from DC to Terahertz frequency range.
  • Circuit-level EM isolation, coupling and crosstalk modeling during design stage and before LVS-clean.
  • Automatic combined layout creation and manual adjustment supported for EM isolation analysis.
  • Full EM model and HPBM back annotation to hierarchical top cell schematic test bench.
  • EM Prototyping™ offers a method to verify and mitigate the EM coupling effect between EM devices and/or interconnects to drastically increase the accuracy and confidence of the high frequency design early on.

EM Isolation Analysis with EM Prototyping™

EM isolation analysis is a specialized field of EM simulation, which focus on the EM design and simulation techniques related to couplings and isolations. For modern RF and 5G SOC designs, EM isolation analysis is essential and critical for sensitive and elusive high speed circuits to ensure design success. 

EM isolation is the ratio of mutual term over self term to measure the coupling effects relative to the source of couplings, and the EM isolation noise floor defines the lowest coupling value that EM tools can capture without losing numerical accuracy or physical meaning. Today, PeakView® is capable of handling severe EM Isolation Analysis needs: 

    • PeakView®’s achieves -110dB for the EM isolation noise floor with the default settings of HCS and FlatLEM solver engine
    • For extreme EM isolation analysis, -130dB represents the maximum EM isolation noise floor. 
    • EM Isolation analysis is also aided by built-in formula, post-processing and visualization/animation features.

Back-Annotation of EM Results to Test Bench

The powerful back-annotation of the EM result to the original schematic enable users to quickly and accurately re-simulate the design with the effect of EM models obtained from the EM prototyping tool. This greatly eliminated the error-prone manual intervention of inserting the EM models into test benches by automatically managing connections throughout design hierarchy.
