01Access confirmedUnconfirmed
Does the sample implement accessible lane margining, error logging, or equivalent DFx information?
Specification support does not establish die implementation. Answer based on actual register, log, or test-interface availability.
Update engineering conditions →02Primary inputs completeUnconfirmed
Are actual PHY, channel, data-rate, clock, and power conditions available for a corresponding model?
A generic model cannot represent the actual D2D channel. Missing data remain model-preparation gaps.
Update engineering conditions →03PersistsUnconfirmed
Do lane errors or margins recover at the original temperature and identical power settings?
Reversible changes prioritize electrical and setting checks. Persistent anomalies raise physical-interconnect sampling priority.

Check the comparison table above for each solution’s specific inputs and applicability limits.
Questions to discuss
- Are errors tied to specific lanes, temperatures, power, rates, or clock settings?

- UCIe Consortium · UCIe 2.0: Continuing Innovation ↗
View source notes and limits
Describes lane margining, fault reporting, and UDA test / debug / telemetry; manageability is optional.
The white paper is not a sample-specific DFx inventory. Confirm implementation and applicable specifications.
- Keysight · Chiplet PHY Designer 2025 standards support ↗
View source notes and limits
The 2025 version adds UCIe 2.0 and BoW simulation support.
This manufacturer capability statement does not establish physical-interconnect failure diagnosis or lifetime prediction for this case.
- UCIe Consortium · Official UCIe white-paper index ↗
View source notes and limits
Official white papers cover multiple specification versions, including UCIe 2.0 and 3.0.
The index provides no case-specific acceptance limits. A 2.0 method does not guarantee compatibility with all later versions.
- Synopsys · SLM UCIe MTR IP for die-to-die monitoring, test and repair ↗
View source notes and limits
The supplier lists JTAG/APB access, custom patterns and eFuse repair records, without enumerating supported UCIe versions.
Scope and limitations Compatible PHY monitors/access hardware must exist; it cannot directly retrofit devices lacking them. Lane repair does not heal physical damage. What to prepare BLNKK suggests PHY/IP versions, lane and access/repair architecture, patterns, and temperature/supply/workload records. Confirm with the supplier Confirm versions, monitors/thresholds, BIST coverage, repair resources, eFuse integration and manufacturing/in-system access flows.
- Ansys, part of Synopsys · HFSS 3D electromagnetic analysis of package transitions ↗
View source notes and limits
The product page names IC-package, S-parameter and interconnect analysis. It does not validate a particular user model against hardware.
Scope and limitations HFSS alone does not cover every thermal/mechanical reliability analysis. Check ports, reference planes and model assumptions; S-parameters do not automatically remove measurement-fixture effects. What to prepare BLNKK suggests preparing dimensions, frequency-dependent materials, frequency range and ports, with same-reference-plane measurements and convergence/loss-sensitivity checks. Confirm with the supplier Confirm solvers, version, modules, imports and circuit links; agree on ports, de-embedding and correlation. For thermal/structural work, confirm separate tools and coupling.
- Advantest · V93000 EXA Scale electrical testing of observable device interfaces ↗
View source notes and limits
Official EXA Scale/SmarTEST descriptions cover characterization, wafer sort and final test.
Scope and limitations Electrical failures do not locate internal joint damage. UCIe lane-margining coverage requires verified DUT test access and observability. What to prepare BLNKK suggests preparing DFx modes, vectors, ports, power needs, contact fixtures, temperature conditions and baseline logs. Confirm with the supplier Confirm channel/power instruments, interfaces, software licensing, thermal-control integration and actual test-mode coverage/correlation.
- Synopsys · PrimeSim HSPICE channel and receiver-margin comparison ↗
View source notes and limits
Named product and SIPI workflow pages document HSPICE I/O modeling/channel roles.
Scope and limitations Models do not locate buried joints or automatically establish UCIe compliance. Confirm PrimeWave, 3DIC Compiler and interface-IP capabilities separately. What to prepare BLNKK suggests documenting driver/receiver models, channel parasitics, supply/operating conditions, versions/corners and measured references. Confirm with the supplier Confirm model support, channel formats, required analyses, companion tools/licenses and margin-to-measurement correlation criteria.
- Amkor Technology · Amkor package design characterization ↗
View source notes and limits
The official service page and electrical service sheet describe these methods and SI/PI analysis supporting package co-design.
Scope and limitations Published capabilities do not imply unrestricted external commissioning or chiplet-protocol compliance. Confirm accessible ports and package boundaries; this does not automatically diagnose on-die causes. What to prepare BLNKK suggests preparing package routing, signal/return paths, available models, failure conditions and measurement calibration/de-embedding data. Confirm with the supplier Confirm project acceptance, sample and confidentiality arrangements, analysis conditions, deliverables and validation criteria.
- Intel Foundry · EMIB local-silicon-bridge 2.5D multi-die packaging ↗
View source notes and limits
The packaging page and July 2025 brief describe local embedded bridges and EMIB production since 2017. EMIB-T, EMIB-M and Foveros-integrated configurations have separate features.
Scope and limitations This entry concerns EMIB 2.5D; other variants are not default features. Published information does not establish warpage or yield for a particular design. What to prepare BLNKK suggests preparing die layout, interconnect density, HBM configuration, power, cooling needs, package dimensions and reliability targets. Confirm with the supplier Confirm EMIB variant, interfaces, design rules, substrate and assembly flow, and test responsibilities. Discuss project availability, capacity and lead time.
