Communication Protocol: gRPC

PyEDB exclusively uses the gRPC Remote Procedure Calls (gRPC) protocol to communicate with the ansys-edb-core service.

This modern framework is the foundation of PyEDB’s architecture and offers key benefits:

• Headless Operation: Enables operation on servers without a GUI (for example Linux, Docker).

• Performance: High-speed communication, ideal for processing large, complex designs.

• Reliability: Robust connection handling and error reporting.

• Decoupled Development: The Python client and the core service can be updated independently.

Checking the Connection

You can always check the status and version of the connection from your Python script.

from pyedb import pyedb

edb = Edb(edbpath="/tmp/my_project.aedb", version="2025.2", grpc=True)

If connection was successful, you should something similar to this in the console:
