Higher-Level Pythonic Ansys Electronics Data Base
Decision gist · record as of 2026-08-14
Yes, if you have a licensed copy of AEDT and need to automate EDB layout workflows. The package is actively maintained, has low install friction, carries no known vulnerabilities, and uses a permissive MIT license. The main constraint is the external dependency on ansys-edb-core and AEDT itself, which limits use to organizations with existing Ansys licenses.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a legally licensed local copy of AEDT (Ansys Electronics Desktop) and ansys-edb-core installed; Python 3.10 or later.
- Low friction: pure Python wheel with no compiled dependencies.
- Active maintenance with a release 19 days old and recent commits.

What it is and what it does
PyEDB is a Python wrapper around Ansys's Electronics Database (EDB) format, designed to make layout automation accessible without deep knowledge of the underlying database implementation. It provides high-level, application-oriented workflows for common tasks like opening or creating EDB projects, editing stackups and materials, managing components and nets, working with padstacks and ports, building cutouts, and preparing designs for electromagnetic solver workflows (HFSS, SIwave, Maxwell, Q3D, Icepak).
The package abstracts backend complexity through a consistent public API, meaning most users can focus on their layout tasks rather than implementation details. It runs as a standalone API without requiring a graphical interface, enabling fast batch processing of large and complex layouts. The package depends on numpy, pydantic, toml, ansys-edb-core, psutil, defusedxml, xmltodict, and typer, and supports Python 3.10 through 3.14.
Use it for
- Automate PCB layout design workflows in batch without opening Ansys Electronics Desktop UI.
- Programmatically edit stackups, materials, and component placement in existing AEDB files.
- Prepare complex layouts for electromagnetic simulation by scripting port and padstack definitions.
- Translate and process large layout designs from external formats into AEDB for solver workflows.
- Build custom design validation or modification tools on top of the PyEDB API.

Before you install
Low friction: pure Python wheel with no compiled dependencies. Active maintenance with a release 19 days old and recent commits. Requires ansys-edb-core as a runtime dependency, which may require a separate Ansys installation.

License in practice
MIT license permits commercial and private use with minimal restrictions. Note that PyEDB itself is licensed permissively, but using it requires a legally licensed local copy of AEDT.
