Glossary

ansys-edb-core

The standalone gRPC service that performs all EDB operations. PyEDB connects to this service as a client. It is also called PyEDB-core.

Cell

Represents the PCB design itself within an EDB project. A project has one active cell. Adding multiple cells is actually adding multiple designs to the same project.

gRPC

A modern, high-performance open-source RPC framework. It is the communication protocol between PyEDB and the ansys-edb-core service.

Layout

The container within a Cell for all the physical data of the PCB (stackup, geometries, components).

Net

A collection of electrically connected pins and primitives (traces, pads) in a layout. Equivalent to a “signal” in schematic terms.

Primitive

A basic geometric shape (polygon, path, rectangle, circle) in an EDB layout.

Stackup

The vertical arrangement of conductive and dielectric layers that make up a PCB.
