BLNKK's current understanding
Please check the details- Structure / bonding interface
- HBM layers and neighboring logic-die thermal paths
- Observation stage
- Workload switching and steady / transient operation
- Phenomenon to localize
- Interlayer or neighboring-die temperature interaction
- Engineering decision
- Use per-layer power, temperature observability, and boundary calibration to select power-distribution, thermal-path, or cooling comparisons
- Sample evidence still required
- Which power / temperature values are measured, estimated, or unobservable by layer?
Paths to assess first
Paths serve different purposes and can be combined01
Load switching and observable-temperature comparisonsCompare a known heat source's response at another observable location
First02
Layered electrothermal models and sensitivityCompare power allocation, cross-layer / in-plane, and interface thermal paths
First03
Cooling / transient-boundary comparisonsCompare cooling and time responses under fixed excitation
FirstCurrent candidate solutions
Sample suitability still needs confirmationRedHawk-SC Electrothermal layered-model evaluationAnsys · Can help answer: Public multi-die capabilities can enter model comparisons; actual power / stack inputs still need calibration.
→Icepak transient and cooling-boundary evaluationAnsys · Can help answer: Public tutorials support time-dependent excitation / fan comparisons. Define the model from the actual stack.
→Joint review of controlled observations and layered modelsBLNKK engineering review request (provider unconfirmed) · Can help answer: Only after all three approaches have inputs, compare power allocation, thermal paths, and cooling controls.
