TinyTapeout Explains How Open-Source Chips Are Factory-Tested Before Shipping
Obijuan_cube · x · 2026-11-12
Open-source silicon project TinyTapeout details its chip validation pipeline:
- In-transit testing: chips are checked for power-up and the factory test design is enabled; signal input-to-output delay plus analog pin resistance and bandwidth are measured.
- Spec updates: accumulated test data feeds into updating the website's specification page and datasheet.
- Post-arrival retest: once chips arrive, breakout boards are built, plugged into dev boards, and factory tests are rerun with all I/O checked.
A full video walkthrough is available.
