| Feature | Proposed GPR Model | Virtual Probe (VP) |
|---|---|---|
| Prediction Accuracy | 9% and 7% higher than Naive GPR | Struggles with precision and recall (0.5 and 0.8) |
| Training Data Required | 50% less training data | Higher data requirements |
| Degradation Detection | 100% accuracy for 10-day and 14-day aged FPGAs | Cannot properly classify all aged/non-aged FPGAs |
| Classification Robustness | Perfect classification with Logistic Regression | Fails completely in some cases |
Real-world Efficiency: Testing 1,000 FPGAs
Implementing the proposed GPR-based approach with 10% sampling reduces total measurement time from 20.83 hours (full sampling) to 2.08 hours, saving nearly 19 hours. This translates to substantial operational benefits, especially in high-volume production or post-deployment inspection scenarios, and for facilities processing 10,000 FPGAs monthly, it could mean labor cost reductions of over 85% (from 208 to 21 hours).
