Signal Integrity Modeling and Simulation
When your design involves high-speed signals, signal integrity (SI) simulation is non-negotiable. At Signal Edge Solutions, we specialize in helping you navigate the complexities of high-speed routing. We provide comprehensive SI simulation and modeling services that ensure your high-speed signals maintain their integrity.
​​
Our services are designed to improve your design's performance by addressing critical issues like crosstalk, jitter, and signal reflections. We'll optimize your transmission line routing and verify that your design meets all required SI compliance standards. By proactively identifying and resolving these issues through simulation, we ensure your design works right the first time, saving you from costly and time-consuming redesigns.
​
Whether you are designing 224G SerDes paths, DDR5 memory interfaces, multi-chip modules, chiplets, multi-chip modules (MCM), custom ASIC packages, FPGAs, PCIes, or complex multi-board systems, our team has the industry-leading tools and expertise to predict and prevent the invisible physics that derail modern hardware.
The SI/PI Model Library
Unlike standard vendor models that are often encrypted, limited to small-signal analysis, or prone to inaccuracies in the high-frequency domain, our library of measurement-based models provides a unified ecosystem of high-fidelity, validated components.
Curated by our Keysight Certified Experts, these models capture real-world non-linear behaviors and complex transients, allowing you to perform end-to-end system simulations with uncompromised precision
End-to-End Signal Integrity Services
Crosstalk Mitigation: As routing densities increase, the risk of electromagnetic coupling grows. We analyze your stackup and trace spacing to eliminate near-end (NEXT) and far-end (FEXT) crosstalk, ensuring clean isolation.
Jitter Analysis: High-speed timing margins are thinner than ever. We characterize deterministic and random jitter components, providing you with the confidence that your clock and data signals will meet their required bit-error rates (BER).
Reflection Management: Impedance mismatches are the root of signal distortions. We perform detailed TDR (Time Domain Reflectometry) simulations to identify discontinuities in vias, connectors, and traces, eliminating signal reflections before they reach the lab.
Transmission Line Optimization: We go beyond simple trace-width calculators. Our team optimizes your transmission line routing by considering frequency-dependent losses, skin effect, and dielectric constant variations.
SerDes Channel Modeling: Our approach moves beyond basic trace analysis to evaluate the full "end-to-end" link, integrating the precise effects of FFE (Feed-Forward Equalization), CTLE (Continuous-Time Linear Equalization), and DFE (Decision Feedback Equalization) within the simulation environment. We calculate the Channel Operating Margin (COM) for your specific architecture, ensuring your design achieves the necessary signal-to-noise ratio and bit-error rate (BER) targets required by 112G and 224G standards.​
Compliance Verification & Sign-off: Don't wait for a failed lab test to discover a design flaw. We provide pre- and post-layout verification to ensure your design meets all major SI compliance standards, including PCIe Gen 5/6, USB4, Ethernet (802.3), and JEDEC DDR specifications.
The Signal Edge Advantage: First Pass Success
Our goal is to eliminate the "re-spin" cycle. By integrating our simulation and modeling services into your design flow, you reduce development time, lower costs, and bring your product to market with the certainty that it will perform in the most demanding environments.
