Electromagnetic (EM) Model Extraction

At Signal Edge Solutions, we recognize that as data rates climb into the multi-gigabit range, every physical structure on your PCB becomes a complex electromagnetic entity. Our Electromagnetic (EM) Model Extraction services are designed to move beyond simplified approximations, providing you with high-fidelity, physics-based models that account for the true behavior of your high-speed signal paths. Using advanced 3D full-wave and quasi-static solvers, we extract the precise parasitic elements that define your system’s performance.

We can perform extractions of high-speed nets like SerDes, LPDDR4/5, DDR4/5, PCIE, UCIe, clocks, USB, and HDMI. We can also extract a full PCB or an advanced package to generate a Touchstone (SnP) model for your team or your customers. These expedited services ensure you have the precise data you need to run accurate simulations and validate your design's performance.

Capturing the Physics of High-Speed Interconnects

We specialize in extracting accurate models for the most "invisible" parts of your design:

High-Speed Via Transitions: We model the complex interaction of signal vias, stitching vias, and anti-pads to minimize impedance discontinuities and resonance.

Connector & Socket Interfaces: We characterize the transition from the PCB to the connector, ensuring that the breakout region (BOR) is optimized for maximum signal transfer.

BGA Fanout & Package Integration: Our simulation services bridge the gap between the silicon die and the PCB, accounting for bumps and package trace parasitics. We specialize in BGA fanout design and optimization, strategically managing the "breakout" region to minimize crosstalk, ISI, and impedance discontinuities in high-density routing. By performing 3D EM simulations of the via-in-pad transitions and escape routing, we ensure that your BGA fanout is optimized for both signal integrity and power delivery, reducing the risk of unintended resonances or excessive voltage drop at the ball-to-board interface.

The SI/PI Model Library

Unlike standard vendor models that are often encrypted, limited to small-signal analysis, or prone to inaccuracies in high-frequency domains, our SI/PI Model Library is coalesced to support end-to-end system modeling with uncompromised precision.

Subscribing ensures your team has immediate access to a constantly growing repository of validated components that capture real-world non-linear behaviors and complex transients, significantly reducing the gap between virtual prototypes and lab measurements.

By centralizing these high-performance models in one place, we eliminate the time-consuming task of troubleshooting unreliable third-party data, allowing you to focus on transmission line optimization and compliance sign-off with the confidence of first-pass hardware success. If we don’t have the model you need yet, we can develop it for you.

Full-Wave Accuracy for Signal & Power Integrity

We leverage industry-leading EM simulation tools, driven by our Keysight Certified Experts, to provide S-parameter and broadband SPICE models that are ready for immediate use in your simulation environment.

Broadband S-Parameter Extraction: We capture the frequency-dependent behavior of your interconnects, including skin effect, dielectric loss, and causality-compliant phase response.

Crosstalk & Coupling Analysis: Our 3D extraction accounts for the complex electromagnetic coupling between traces and planes, providing a true-to-life representation of near-end and far-end crosstalk.

Resonance Identification: We identify unintended cavity resonances and "floating" metal structures that can lead to catastrophic EMI or SI failures at high frequencies.

The Signal Edge Solutions Standard

Signal Edge Solutions’ industry recognized team, including Keysight Certified Experts, utilizes advanced laboratory instrumentation to extract high-fidelity data directly from your hardware. By correlating empirical VNA and oscilloscope measurements with our 3D electromagnetic extraction, we deliver models that capture the true "end-to-end" physics of your signal and power paths. This measurement-backed approach eliminates the guesswork of "black-box" simulation, providing the transparency and accuracy required to achieve first-pass hardware success and meet the most stringent PCI-SIG and JEDEC compliance standards.
