README

sim-plugin-hfss

Use Codex, Claude Code, or another AI agent to work with [Ansys HFSS](https://www.ansys.com/products/electronics/ansys-hfss) 3D projects through [sim-cli](https://github.com/svd-ai-lab/sim-cli).

`sim-plugin-hfss` is an initial HFSS 3D driver plugin for sim-cli. It uses PyAEDT as the Python control layer for Ansys Electronics Desktop (AEDT), keeps the driver import-safe on machines without AEDT, and bundles an HFSS agent skill so an agent has solver-specific workflow guidance after installation.

The HFSS/AEDT application is not bundled. See [LICENSE-NOTICE.md](LICENSE-NOTICE.md).

Current maturity

This is an initial alpha release. It has unit coverage, protocol conformance coverage, simulated PyAEDT session coverage, packaging checks, and opt-in real HFSS smoke coverage for hosts with AEDT available.

Use it as an integration starting point, not as proof that a production HFSS workflow has been validated end to end.

Scope

Version 0.1.2 targets HFSS 3D through PyAEDT's `ansys.aedt.core.hfss.Hfss` interface.

Out of scope for this first version:

HFSS 3D Layout
Maxwell, Icepak, Q3D, Circuit, or generic AEDT workflows
Direct .aedt or .aedtz batch solve without a PyAEDT script
Plugin-index catalogue entry before the package is published and smoke-tested

What an agent can do with HFSS

Detect PyAEDT Python scripts that instantiate HFSS.
Check whether AEDT appears to be installed on the host.
Run an experimental offline .aedt/zip-packaged .aedtz probe for project names, design hints, variables, setups, ports/boundaries, lock files, and .aedtresults sidecar progress without launching AEDT.
Start a PyAEDT-backed HFSS session in graphical or non-graphical mode when AEDT is available.
Execute bounded Python snippets against the active hfss object.
Preserve and reattach an Agent-owned AEDT process by PID when a bounded Python control call times out.
Inspect session, project, and design summaries before
