Python CIRCT Design Entry (PyCDE)

PyCDE is a Python API for designing hardware with CIRCT, the Circuit IR Compilers and Tools project. It provides Python syntax for constructing hardware modules, connecting typed signals, and generating SystemVerilog using CIRCT's compiler infrastructure.

Installation

PyCDE requires Python 3.10 or newer.

pip install pycde

Getting started

See the PyCDE documentation for a hello-world example, and the basics guide for modules, signals, types, and interoperability with existing hardware.

For building from source, see the compilation guide. PyCDE is developed as part of the CIRCT repository.
