HFSS 3D electromagnetic analysis of package transitions

Ansys, part of Synopsys · Thermo-mechanical simulation and lifetime prediction

Purpose: Compare package-transition loss and crosstalk using geometry, materials and measurement ports together in a 3D EM model.
Technical approach: Full-wave solving with adaptive meshing calculates fields and S-parameters. Circuit links extend interconnect SI/PI analysis.
Scope of use: For package traces, vias, interposers and RF transitions with usable geometry, frequency-dependent materials and defined ports; verify version/licensing.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
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.
Public evidence: The product page names IC-package, S-parameter and interconnect analysis. It does not validate a particular user model against hardware.
