ZeroSoC is a RISC-V SoC designed to demonstrate the capabilities of SiliconCompiler. ZeroSoC consists of an Ibex core, UART and GPIO peripherals from the OpenTitan project, and 8 KB of RAM.
Clone the repository and all its submodules:
$ git clone [email protected]:siliconcompiler/zerosoc.git
$ cd zerosoc
$ git checkout stable
$ git submodule update --init --recursive
$ pip install -r python-requirements.txtBuilding ZeroSoC locally for ASIC or FPGA targets requires installing external tools. This page contains links to installation instructions for SC's supported tools. The build script also supports remote builds, which do not require installing additional tools.
Note: The ZeroSoC tip of main is considered unstable and may not be
compatible with the latest SiliconCompiler. To ensure compatibility, we
recommend checking out the stable tag and using the most recent
release version of SC.
build.py is ZeroSoC's build script, based around the SiliconCompiler Python
API. Running this script with no options initiates a local ZeroSoC ASIC build,
and runs DRC and LVS on the final GDS.
Running build.py --help gives information on additional options:
-h, --help show this help message and exit
--core-only Only build ASIC core GDS.
--top-only Only integrate ASIC core into padring. Assumes core already built.
--floorplan Break in floorplanning steps
--verify Run DRC and LVS.
--remote Run on remote server. Requires SC remote credentials.
