BLNKK's current understanding
Please check the details- Package architecture
- Chiplet / 2.5D or 3D; D2D PHY and interconnect type unconfirmed
- Observation
- Lane errors or margin changes after temperature changes
- Evaluation stage
- Post-package functional testing, temperature sweeps, or thermal cycling; distinguish reversible drift from accumulated damage
- Variables to validate
- Clock, power, channel, PHY settings, and interconnect continuity
- Missing information
- UCIe version, DFx implementation, lane logs, temperature and power history, and good-sample controls
Paths to assess first
