How this works
Read tab-separated MPN, Qty and Ref columns. Preserve each row and full MPN. Count explicit reference tokens; flag duplicates without merging or expanding ranges.
BOM & sourcing / T141
BOM completeness check
Check pasted BOM rows for missing values, quantity mismatches and duplicate references.

Ready for an example run. Check the inputs, then run the tool.
Row issues, missing values and duplicate references
- Confirm the values and units.
- Run the check to generate your output.
- Review limitations before exporting or sharing.
Calculation & record
Review before use
The report records the tool version and calculation time. Project enquiry opens a separate form for your review; it does not submit automatically.
03 / METHOD & VERIFICATION
Understand the result.
Method version 1 · 2026-09-27
FPGA.io planning aid. Arithmetic and checklist output do not replace device documentation, a design tool or engineering approval.
Inputs and limits
Header plus 1–500 rows; up to 100,000 characters; whole positive quantities. Use explicit references, not U1–U10 shorthand. Processing remains in your browser.
Verification example
A row with Qty 2 and only U1 is flagged; U1 repeated on another row is also flagged.
Use the example inputs to inspect how the method behaves. This is a reference calculation, not a hardware test.
Data handling & review
Calculations and pasted lists stay in this browser. No account is required. An enquiry brief is stored temporarily in this tab's session only when you choose to transfer it.
