Schematic review · before layout

A senior engineer checks your schematic before you pay for a respin.

Send the PDF and BOM. You get a fixed quote, then a severity-rated report where every finding names the designator or net and the datasheet reason behind it.

DocumentReview report · example
Sheet3 of 12 · Power
HIGH U7 · pin 14 · VDDIO_1V8 No local decoupling on this rail. The datasheet asks for 100 nF placed at the pin; without it the I/O bank can brown out on burst traffic.
MEDIUM R42 / R43 · BOOT_MODE[1:0] Both straps are pulled up to 3V3 while the SoC samples them against 1V8. Level and default mode need a second look.

How it works

Four steps, one fixed price

  1. Send your files

    Schematic PDF and BOM (CSV or Excel). Native Altium files are welcome. We sign your NDA or send ours.

  2. Get a fixed quote

    Within one business day, based on sheet count and complexity. No hourly surprises.

  3. We review

    Every sheet is checked against the datasheets and against the rules that make boards come up on the first spin.

  4. Report and follow-up

    A PDF report ranked by severity, then one round of questions answered by e-mail.

What we check

The places boards fail on the first spin

Power treeSequencing, rail margins, regulator stability, inrush
Resets and strapsBoot modes, pull levels, reset timing and polarity
ClocksFrequencies, load caps, spread, routing notes
High-speed interfacesDDR, PCIe, USB, Ethernet: terminations and pin maps
FPGA and SoC I/OBank voltages, reserved pins, configuration
ProtectionESD, reverse polarity, fuses and clamps at every connector
DecouplingValues and counts against each datasheet
Analog and mixed-signalReferences, grounding, ADC front ends

Out of scope: RF and antenna design, PCB layout review, firmware.

Who reviews

One principal-level board designer, 30 years in shipping hardware

  • Consumer wearables and SoC boards built at volume
  • LiDAR, embedded vision, FPGA and MPSoC systems
  • Medical devices and defense-grade IR imaging
  • Engineer-led and tool-assisted: automated checks catch the mechanical errors, the engineer signs every finding
Sample reports

First sample report in preparation

We are reviewing a public open-source FPGA board end to end. The full report will be posted here, so you can see the depth of a review before you buy one.

Questions

Before you send files

What do I need to send for a schematic review?

The schematic PDF with all sheets, the BOM as CSV or Excel, and one line on what the board does and what worries you most. Native Altium files are welcome but not required.

How fast is the review?

A Quick Check (boards up to about four sheets) comes back within 48 hours. A Full Review takes 3 to 5 business days after the quote is accepted.

How much does a schematic review cost?

Quick Check is USD 195. A Full Review starts at USD 650 and is quoted as a fixed price before any work starts, based on sheet count and complexity.

How is my design kept confidential?

We sign your NDA or send ours before files are opened. Client files are handled under NDA, stored in access-controlled folders, and deleted on request. We use AI tools only with model training turned off.

Who reviews the schematic?

A principal-level board designer with 30 years of shipping hardware: consumer wearables and SoC boards, LiDAR and embedded vision, FPGA and MPSoC systems, medical devices and IR imaging. Reports are signed 1997circuits Engineering.

Do you use AI tools?

Yes, as assistants. Automated checks parse the netlist and BOM and compare pins against datasheets; the engineer confirms or rejects every finding and signs off the report. Engineer-led, tool-assisted.

What is out of scope?

RF and antenna design, PCB layout review, and firmware.

Can Korean hardware teams use the service?

Yes. Inquiries and report walk-throughs can be in Korean, and payment in KRW is available.
