In-Design SI / PI Analysis for the PCB Designer
Sigrity Aurora for PCB
Design, simulate, fix, and verify in real time — embedded Sigrity SI and PI engines inside the PCB canvas. Identify and resolve issues at any stage, in context, without leaving your layout environment.
Overview
Identify & Fix SI / PI Issues in Context
Sigrity Aurora enables collaborative work between PCB designers, electrical engineers, and SI experts — identify and fix common SI / PI issues in the design canvas at any stage. Quickly perform analysis, view overlaid simulation results on your layout, and verify fixes inline.

Key Features
12 Analyses, One Canvas
Sigrity Aurora puts a full SI / PI / thermal analysis toolset inside your PCB layout — no separate tool, no separate environment, no SI expert required.
Impedance Analysis
Detect and resolve impedance discontinuities and high-impedance traces in the PCB canvas to improve signal quality.
Coupling Analysis
Manufacture reliable products by detecting and correcting coupling issues — no SI expert required.
Reflection Analysis
High-speed designs are susceptible to reflection and ringing — analyse simulation-driven results to correct as you design.
Crosstalk Analysis
Resolve data-transfer corruption by analysing crosstalk and increasing spacing for detected aggressor traces.
Return Path Analysis
Detect inconsistencies between signals and return paths that could degrade functionality — visual results on canvas.
IR Drop Analysis
Simulate and visualise IR drop to improve power integrity — catch field failures from copper-plane changes before they ship.
Topology Extraction
Extract high-speed signals as S-parameter models for further simulation — time-domain, eye diagrams, channel verification.
Automated Design Setup
Step-by-step workflow configures the design and simulation settings — accurate and efficient analysis with minimal setup.
Interconnect Model Extraction
S-parameter models of packages and interposers to understand SI degradation and its effect on signal groups.
Thermal Analysis
Identify possible hotspots based on component power dissipation — calculate thermal stress and failure risk inside the canvas.
Virtual Prototyping
Create a virtual prototype — no netlist required — to test concepts, placement, SI/PI requirements, and constraints.
Power Inductance Analysis
Step-by-step procedure to analyse power / loop inductance — optimize decaps, identify weak pins, build a responsive PDN.
