LIMERICK, Ireland, November 14th - yieldHUB, the Irish semiconductor yield management company, has set out how real-time semiconductor test data helps chip makers get more output from the testers they already own. Director of Growth Gillian O’Donnell explains the approach in episode 258 of the AI Ireland podcast, published on 12 November 2026. The company’s real-time product, yieldHUB Live, has been nominated for Agentic AI Innovation of the year.
What yieldHUB Live does
yieldHUB Live is real-time test floor software that monitors semiconductor testers while a lot is still running. It alerts engineers and operators to tester idle time, yield drops, site issues and unnecessary retest, and it recommends the next action.
Lightweight software runs on each tester, modern or legacy. It needs no test program changes, adds no test time and requires no extra hardware. It runs in the cloud or on-premise.
The timing is the difference. A manufacturing execution system (MES) can depend on manual status updates, so it may show a tester as running when it is idle. yieldHUB Live reads what the tester is doing at that moment.
Proven in high-volume production
Allegro MicroSystems uses yieldHUB Live at its final test operation in the Philippines, the highest-volume site in its manufacturing network. Allegro targeted a one percentage point gain in overall equipment effectiveness (OEE). It achieved several points and sustained them.
Less unnecessary retest and less idle time also raised first pass yield. Direct variable cost savings from smart retest exceeded the full-year projection. Comparing 20 lots now takes minutes, down from half a day or more of engineering time.
“It increased capacity, so we are able to delay the acquisition of more equipment,” said Eunice Esguerra, Section Manager for Final Test Product Engineering at Allegro MicroSystems Philippines.
Allegro’s own team is now rolling out yieldHUB Live across dozens of additional testers.
Smarter manufacturing starts with trusted data
“Every test operation we speak to is being asked for more output from the same floor,” said Gillian O’Donnell, Director of Growth at yieldHUB. “The capacity is often already there, hidden in idle time and retest. Real-time data shows engineers where it is while they can still act on it. That same clean data is what makes AI in manufacturing reliable.”
yieldHUB was founded in Ireland in 2005 and serves fabless companies, IDMs and OSATs across Europe, the USA, Asia and the Middle East.
Questions and answers
By recovering time lost to tester idle time and unnecessary retest. Allegro MicroSystems recovered enough capacity with yieldHUB Live to defer equipment purchases.
No. yieldHUB Live adds no test time and needs no test program changes. Allegro reported no measurable test-time impact.
An MES records the status it is given. yieldHUB Live measures tester activity directly, so it reports true idle time and yield as they happen.
