We don’t just check your signals — we make them work right the first time.
When speed increases, margins shrink — and signal failures get expensive.
We help you detect, diagnose, and eliminate signal integrity and EMC issues before they escalate. Whether you’re dealing with jitter, eye diagram collapse, or failing EMI tests, our combined approach of simulation and real-world measurement ensures your board performs — and certifies — as intended.
High-speed boards don’t forgive mistakes. If your design is already in trouble — or if you’re trying to avoid a costly certification failure — you’re in the right place. These are the real-world challenges our clients bring to us:
You’re approaching production, but the product can’t pass EMC Directive 2014/30/EU, FCC, or MIL-STD-461 due to excessive conducted or radiated emissions. We provide a structured audit, pinpoint root causes, and guide you through pre-compliance and final certification.
Random failures, signal collapse, or timing violations? We analyze jitter, eye diagrams, S-parameters, and BER to identify signal degradation, impedance mismatches, or design flaws — and fix them before they escalate.
Your PCIe, DDR, USB 3.2, or Ethernet 10G+ links don’t initialize reliably or produce intermittent bit errors. Our engineers specialize in high-frequency signal integrity, controlled impedance routing, and differential pair tuning to restore clean communication.
When your eye diagram collapses, you’re out of margin. We use real-world measurements (not just simulations) to test and visualize your signal window, evaluate timing jitter, and apply layout or termination corrections that open the eye.
You need engineers who go beyond theory. We combine SPICE models, full-wave field solvers, and lab-grade real-time instruments — so you get both prediction and verification. Because only a measured signal is a trusted signal.
Bottom Line: Whether you’re in pre-certification panic mode or building for 100 Gbps from day one — we’ll help you solve what others missed.
We offer a complete signal integrity and EMC optimization service — from the first trace audit to passing your final compliance test. Unlike labs that only simulate, or test houses that just report failures, we bridge both worlds to ensure your board performs as designed, as measured, and as certified.
• Trace Routing Audit Focused on SI/EMC Performance
We perform a comprehensive review of your PCB layout and schematics — analyzing controlled impedance, differential pair symmetry, return paths, and clock domain crossings. Every trace is examined for physical and functional signal behavior under real conditions.
• S-Parameters, BER Testing, and Eye Diagram Analysis
We extract S-parameters to model high-frequency effects, measure Bit Error Rates (BER) on live interfaces, and evaluate eye diagrams with lab-grade oscilloscopes — giving you visual, numerical, and frequency-domain validation of signal quality.
• Jitter Analysis and Root-Cause Mitigation
We break down total jitter (TJ) into its components — random jitter (RJ) and deterministic jitter (DJ) — using real-time scopes and compliance-grade software. From via stubs to power integrity ripple, we isolate and eliminate root causes, not just symptoms.
• Pre-Compliance Testing for Conducted and Radiated Emissions
Before you go to the lab, we help you pass — conducting near-field scans, spectrum analysis, and filter topology review to ensure your board meets CISPR, FCC, and CE radiated/conducted emission thresholds.
• Stackup, Grounding, Shielding, and Filtering Optimization
We engineer your PCB from the core: optimizing layer stackups for signal return paths, designing ground isolation strategies, adding or tuning shielding enclosures, and selecting filters or chokes to mitigate unwanted harmonics and noise coupling.
Result: You get data-driven signal integrity, EMC readiness, and documentation that speaks the language of certification bodies.
Our signal integrity and EMC methodology is designed to eliminate uncertainty and deliver actionable outcomes. Whether you’re optimizing for certification or troubleshooting live failures, we apply a structured, repeatable process — grounded in both simulation and real-world measurement.
We begin by understanding your system architecture: interface types, data rates, standards (e.g. PCIe, USB, DDR, Ethernet), target certifications (CE, FCC, MIL-STD-461), and frequency ranges. This step defines test boundaries and simulation objectives.
We review your design files to identify impedance mismatches, return path violations, via stubs, clock domain crossings, and aggressive signal transitions. This audit forms the baseline for simulation and measurement.
Using professional tools (HFSS, HyperLynx, Keysight ADS), we simulate:
S-parameters for insertion/return loss
Impedance profiles across differential pairs
Jitter impact from layout geometry or power noise
Crosstalk and reflection risk based on trace geometry and stackup
We complement modeling with real-world data:
Eye diagram analysis on high-speed interfaces
Bit Error Rate (BER) testing under loaded conditions
Spectrum analysis for pre-compliance EMC scans
These measurements bridge the gap between theory and reality.
We deliver a structured report that includes:
Detailed SI/EMC findings
Annotated layout screenshots
Simulation vs. measurement comparison
Specific, prioritized action items
Guidance for certification success
From first measurement to final fix — we provide the numbers, not just opinions.
When it comes to signal integrity and EMC, you need more than simulations — you need hard data. That’s why our team combines deep engineering expertise with direct lab measurements, delivering results that hold up not just in theory, but in certification labs and the real world.
• We work with interfaces up to 100 Gbps
From legacy buses to bleeding-edge protocols, we support high-speed signaling standards including PCIe Gen4/5, USB 3.2, DDR4/5, SATA, 10G/40G/100G Ethernet, and more. Our lab is equipped for sub-picosecond jitter analysis and GHz-range signal fidelity testing.
• Simulation is just the start — we measure everything
We use leading EDA tools for signal modeling, but the real value is in our measurements: eye diagrams, BER, S-parameters, and time-domain reflectometry (TDR). We confirm what the model predicts — or expose what it missed.
• Our team knows industry standards inside and out
Whether you’re targeting CE, FCC, EMC Directive, or MIL-STD-461, we understand the requirements. Our designs and reports are aligned with certification bodies and testing labs.
• Our reports are trusted by certification partners
We don’t just deliver data — we document and format it in a way that supports your pre-compliance or final certification process. That includes annotated eye diagrams, impedance plots, and actionable remediation plans.
• We don’t guess. We measure. We fix.
Trouble with jitter, timing closure, or failing EMC? We provide root cause analysis, design corrections, and validated fixes — so you move forward with confidence, not assumptions.
Yes. We audit both schematics and PCB layouts for trace integrity, impedance mismatches, improper pairs, and clock domain crossings.
In signal integrity and EMC work, technical precision means little without legal and ethical precision. We hold ourselves to the highest standards — not only in simulation and measurement, but in how we handle intellectual property, certification processes, and third-party hardware.
• European Directives:
We align our work with the EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU, ensuring readiness for CE marking and EU conformity.
• International and Industry Standards:
Our measurement methods and report formats comply with CISPR, IEC 61000, ISO 7637, and MIL-STD-461 — essential for products in automotive, defense, and industrial sectors.
• Certification-Specific Rules:
We tailor our design reviews and test prep to meet FCC, CE, or custom regional EMC rules — helping you pass smoothly on the first attempt.
• Data Protection and Legal Due Diligence:
We strictly enforce NDAs, adhere to export control laws, and verify IP ownership before engaging in any reverse engineering, layout review, or firmware-sensitive work.
• We never falsify test results or present simulation output as physical measurement when lab-grade data is expected.
• We do not promise EMC certification without conducting a thorough audit of your layout, stackup, and schematics.
• We never copy or reuse protected designs, firmware, or schematics unless the client holds verified legal ownership.
• We do not bypass legal procedures related to reverse engineering, design replication, or modification of third-party hardware.
All services — including impedance-controlled routing, jitter and S-parameter modeling, eye diagram analysis, and EMC optimization — are carried out with full transparency, legal alignment, and traceability.
Before working on any legacy board, confidential system, or imported hardware, we confirm that the client has the legal right to request diagnostics, modification, or reproduction.
We don’t just talk theory — we deliver results. Here are real examples of how our signal integrity and EMC expertise helped clients solve critical challenges and pass demanding certification thresholds.
PCIe Trace Optimization at 10 Gbps
A client’s board failed compliance testing due to excessive jitter and crosstalk on a PCIe Gen3 interface. We performed a full SI audit, redesigned the layer stackup, adjusted controlled impedance, and rebalanced trace spacing. Result: signal stability restored, certification passed, and product released on schedule.
Eye Diagram Over Guesswork
Working on a mixed-interface board with USB 3.0, DDR4, and CAN, our team captured eye diagrams on a real prototype. A critical 3.4 ns timing spike was discovered — not visible in the original simulation. After selective trace rerouting and termination adjustment, the waveform was stabilized, restoring setup and hold margins.
S-Parameters and EMC Strategy for a Custom Telemetry Board
A client developing a high-frequency telemetry system on a nonstandard stackup needed pre-certification help. We modeled S-parameters and jitter behavior under real load conditions, then implemented targeted filtering and return path corrections. The board passed radiated emissions testing — without needing a physical shield.
Emergency Board Stabilization Before Public Demo
A startup preparing for a major trade show contacted us six days before launch. Their board suffered from voltage dips, ground bounce, and ringing on key high-speed lines. We conducted overnight routing stabilization, performed on-site live measurements, and provided a compliance-ready report. Their demo proceeded flawlessly.
Signal integrity isn’t optional — it’s fundamental. And in high-speed systems, small issues compound quickly. You either meet the spec or you fail the test — there’s no middle ground.
Whether you’re preparing for certification, debugging jitter, or planning your next revision, we help you uncover hidden risks early — before they cost you time, compliance, or reputation.
