FPGAs in Production: Cost, Qualification and Change Control
Yenra | Updated September 17, 2026
Article: https://yenra.com/fpga/

Purpose: Compare FPGA production plans and retain the evidence needed for a controlled release. Obtain current supplier quotations; the example is fictional.
Product requirements and lifetime volume: low / expected / high:
Option A and B exact device/order codes:
Fixed engineering, tooling and qualification costs (currency):
Recurring device, programming, test and loss costs per shipped unit:
Total = fixed + quantity x recurring:
Break-even quantity = extra fixed cost / recurring saving (positive saving required):
Example A $40,000 + $60Q; B $240,000 + $40Q. Crossover 10,000 units; both $640,000. At 5,000: $340,000 and $440,000. Equal yield assumed; financing and revision costs excluded.
Design revision scenario, cost and schedule:

Released source/constraints/IP/tool versions:
Bitstream hash and reproducible build record:
Timing, functional and production-test evidence:
Exact qualification evidence and scope:
Supplier-permitted changes and retest triggers:
Lifecycle notice source and date checked:
Decision, unresolved gaps and owners:
