Design Reviews & Compliance Support for Embedded Products

Most costly engineering failures are preventable.


A board respin can cost:

  • $10,000–$150,000+
  • 6–12+ weeks of lost engineering time
  • Missed purchase orders or lost revenue


A failed compliance test (FCC, EMC, UL, CE) can stall a launch for months.


At Simple Innovations, we help embedded engineering teams avoid expensive surprises by performing structured, engineering-led design reviews, compliance planning, and risk reduction throughout the entire product lifecycle.


We don’t just look at schematics.

We evaluate the whole system — architecture → hardware → firmware → manufacturability.



You get confidence that your product will:

  • Pass certification
  • Survive in the field
  • Scale into production without redesign

More than engineering — disciplined, predictable execution that protects budgets, timelines, and outcomes.

What This Service Includes

Hardware Design Reviews

We examine:

  • Schematic accuracy and functionality
  • Power integrity
  • Noise, grounding, and shielding
  • Component selection and lifecycle risk (EOL / availability)
  • PCB layout and routing best practices

Embedded Firmware Code Reviews

We analyze:

  • Code structure and maintainability
  • Efficiency and resource utilization (memory, CPU load)
  • Misalignment between firmware and hardware intentions

Design-for-Manufacturing (DFM) & Design-for-Test (DFT)

We ensure:

  • The PCB can be manufactured without costly manual steps
  • The product can be tested in production environments
  • JTAG / SWD / test pads are placed correctly

Compliance & Certification Readiness

We prepare you for:

  • FCC / CE EMC compliance (radiated/conducted emissions, ESD, RF performance)
  • UL and IEC safety requirements
  • Environmental or regulatory constraints (temperature, vibration, drop)

Risk Mitigation & Action Plan

Every review includes:

  • Findings ranked by severity (Critical / Major / Recommended)
  • Corrective actions with suggested solutions
  • Visibility into cost + timeline impact

Our goal:

 Zero surprises at production.

Why Compliance & Design Reviews Matter

Embedded devices fail certification or require redesigns due to:

  • Incorrect grounding strategy
  • EMI noise coupling into sensitive traces
  • Firmware timing issues that affect peripherals
  • Component placement that violates RF spacing requirements
  • Missing isolation or surge protection in power circuits

These issues aren’t obvious to junior engineers or generalists.


But our team designs and reviews embedded systems every day.


The simple math:

$1 spent on early review saves $50–$100 during redesign.

Types of Reviews We Offer

Review Type When It Happens What It Prevents
Pre-Schematic Review Before schematic capture begins Incorrect architecture decisions
Schematic Review Before layout Component errors, incorrect pin mappings
PCB Layout Review Before sending to fab EMI issues, manufacturability problems
Firmware Code Review During bring-up Integration failures, performance bottlenecks
Pre-Compliance Review Before official testing Failed certification, expensive retests

Examples of Problems We Catch Early

❌ Not enough thermal relief on high-current paths



Fix: wider traces, copper pours, heat sinking strategy.

❌ Improper isolation between high-voltage and low-voltage domains


Fix: clearance / creepage spacing requirements.

❌ Missing test points means production testing becomes manual


Fix: add access points, increase test automation.

❌ Noise from switching power supply coupling into ADC lines


Fix: grounding partition, trace separation, filtering.

These small fixes can save:

Thousands of dollars in redesigns

Weeks or months in delivery delays

Our Compliance Support Process

01

Discovery & Documentation Review

We gather:

  • Requirements
  • Schematics
  • Firmware source code (optional)
  • PCB stackups
  • Target compliance requirements (FCC, CE, UL, etc.)


Deliverable:

 ✔ Scope + review plan

02

Technical Review

We analyze the system using:

  • ERC/DRC checks
  • Signal integrity evaluation
  • Grounding / EMI simulations (as needed)
  • Firmware review tools


Deliverable:

 ✔ Design review report (annotated findings)

03

Risk Prioritization

Each issue is scored based on:

  • Impact (cost/time)
  • Likelihood
  • Severity


Deliverable:

 ✔ Risk matrix with recommended next steps

04

Remediation Support

We collaborate with your team to:

  • Fix errors
  • Update schematic/PCB/firmware
  • Improve testability


Deliverable:

 ✔ Updated design

05

Pre-Compliance Testing

If needed, we perform initial testing for:

  • Emissions
  • Radiated susceptibility
  • Surge/ESD testing (partner lab network available)


Deliverable:

 ✔ Compliance readiness report

Tools We Use in Review

  • Altium Designer
  • OrCAD
  • KiCad
  • Mentor/Siemens EDA
  • Git / GitLab / Bitbucket
  • Code review platforms


If your team uses proprietary or NDA-protected tools — we sign NDAs as standard practice.

Who This Service Is For

This service is ideal if you:

  • Are preparing for FCC / CE / UL certification
  • Have experienced multiple prototype redesigns
  • Don’t want to pay for another board respin
  • Need a second opinion before committing to layout


Common customer problems:

  • “We already built the board but it doesn’t behave correctly.”
  • “Our firmware team blames hardware, hardware blames firmware.”
  • “Certification keeps failing and we don’t know why.”


We break the cycle.

Why Simple Innovations

Deep embedded specialization.

We are not generalist designers. We live and breathe embedded systems.

Hardware + firmware excellence.

We review how code and hardware interact — not just one or the other.

Design ownership.

We don’t just suggest fixes. We help you implement them.

Midwestern integrity + national-level ability.

You get responsiveness, transparency, and reliability.

Pricing (Value-Based, Not Hour-Based)

We offer:

  • Fixed-fee design reviews (based on board complexity)
  • Optional add-ons (pre-compliance testing, lab coordination)


You will always know:

  • What you're paying for
  • What deliverables to expect
  • When to expect them


No surprises.
