Accurate PCB EM Models for Downstream Analysis
Sigrity X PCB Extraction Option
High-accuracy PCB extraction that generates S-parameter macromodels for downstream SI / PI / EM analysis. Feed hyper-accurate models into your channel sims, signoff flows, and full-system analyses.
What It Does
Hyper-Accurate PCB Models, Built for Signoff
The PCB Extraction Option generates broadband, SPICE-ready electromagnetic models from your PCB designs — capturing the full electrical behaviour of interconnects including losses, coupling, parasitics, and return paths.
Those models then feed downstream Sigrity X analyses — SI for serial / parallel bus channels, PI for PDN signoff, and full-system characterisation.
Capabilities
Built for Sigrity X Signoff
Hyper-Accurate Models
Broadband S-parameter models that capture interconnect behaviour from DC through multi-GHz — losses, coupling, return paths.
Built for Speed
Optimised extraction times even on large, dense PCB designs — leverages the Sigrity X parallelised architecture.
Feeds Sigrity X Flow
Output drops into Sigrity SI, PI, and EM analysis flows — and into industry-standard SPICE-based simulators.
Channel Modelling
Extract complete signal channels — vias, traces, planes, decaps — as ready-to-use S-parameter blocks for SerDes signoff.
PDN Modelling
Generate accurate PDN macromodels for downstream PI analysis — impedance signoff, decap effectiveness, resonance.
Full-Board Capacity
Handle high-pin-count, multi-layer PCBs without simplification — full-board extraction with low memory footprint.
Workflow
From PCB Layout to Signoff Models
Import PCB Layout
Bring in your PCB layout from Allegro X, OrCAD X, Altium, Mentor, Zuken, IPC-2581, or ODB++.
Extract S-Parameters
Define ports and frequency range, then extract broadband S-parameter macromodels — fast, full-board, hyper-accurate.
Analyse Downstream
Use the models in Sigrity Advanced SI, OptimizePI, or any SPICE-compatible simulator for signoff-grade analysis.
