BLNKK's current understanding
Please check the details- Structure / observation location
- Adjacent passive aggressor/victim interconnects on the interposer
- Observation stage
- Routing design and passive multiport validation
- Phenomenon to localize
- NEXT/FEXT or adjacent-line-dependent coupling
- Engineering decision
- Use passive multiport and geometry data to determine comparisons of spacing, return paths or isolation routing
- Sample evidence still required
- How can actual passive aggressor/victim lines be aligned with ports, terminations and frequency bands?
Paths to assess first
Paths serve different purposes and can be combined01
Passive multiport coupling and referencesReview actual ports, passive excitation and victim responses, separately from PHY margins.
First02
Adjacent-line/return-path EM model preparationPrepare spacing/return-path comparisons using actual geometry and model settings, without prescribing general rules in advance.
First03
Port and termination comparison preparationPrepare excitation comparisons using actual multiport/termination baselines, pending valid coupling observations.
FirstCurrent candidate solutions
Sample suitability still needs confirmationCheck HFSS inputs for package adjacent-line modelsAnsys · Can help answer: The current HFSS page lists IC-package and interconnect full-wave/SI workflows. First confirm whether actual geometry, materials and port-solver settings support this passive comparison.
