siliconcompiler

Introduction

SiliconCompiler is a modular hardware build system ("make for silicon"). The project philosophy is to "make the complex possible while keeping the simple simple".

Getting Started

SiliconCompiler is available as wheel packages on PyPI for macOS, Windows and Linux platforms. For working Python 3.8-3.12 environment, just use pip.

python3 -m pip install --upgrade siliconcompiler

Converting RTL into DRC clean GDS takes 10 lines of simple Python code.

from siliconcompiler import Chip                   # import python package
from siliconcompiler.targets import skywater130_demo
chip = Chip('heartbeat')                           # create chip object
chip.use(skywater130_demo)                         # load a pre-defined target
chip.input('heartbeat.v')                          # set input sources
chip.clock('clk', period=10)                       # set constraints
chip.set('option','remote', True)                  # enable remote execution
chip.run()                                         # run compilation
chip.summary()                                     # print summary
chip.show()                                        # show layout

Simple designs can be compiled in a single line using the built in command line 'sc' app:

sc -remote -target "asic_demo"

Why SiliconCompiler?

• Ease-of-use: Programmable with a simple Python API
• Portability: Powerful dynamic JSON schema supports ASIC and FPGA design and simulation
• Speed: Flowgraph execution model enables cloud scale execution.
• Friction-less: Remote execution model enables "zero install" compilation
• Modularity: Tool abstraction layer makes it easy to add/port new tools to the project.
• Provenance: Compilation manifests created automatically during execution.
• Documented: An extensive set of auto-generated high quality reference documents.
• In-use: Actively used by Zero ASIC for commercial tapeouts at advanced process nodes.

Installation

Complete installation instructions are available in the Installation Guide.

To install the project from source (recommended for developers only).

git clone https://github.com/siliconcompiler/siliconcompiler
cd siliconcompiler
python3 -m pip install -e .             # Required install step
python3 -m pip install -e .[docs,test]  # Optional install step for generating docs and running tests

EDA Tool Installation

Installation instructions for all external tools can be found in the External Tools section of the user guide. We have included shell setup scripts (Ubuntu) for most of the supported tools. See the ./setup directory for a complete set of scripts and ./setup/_tools.json for the currently recommended tool versions.
