@@ -10,89 +10,9 @@ Welcome to Chipyard's documentation!
Chipyard is a framework for designing and evaluating full-system hardware using agile teams.
It is composed of a collection of tools and libraries designed to provide an integration between open-source and commercial tools for the development of systems-on-chip.
New to Chipyard? Jump to the :ref:`Chipyard Basics` page for more info.
Quick Start
===============================
.. IMPORTANT:: **New to Chipyard?** Jump to the :ref:`Initial Repository Setup` page for setup instructions.
System Requirements
-------------------------------------------
Chipyard is developed and tested on Linux-based systems.
.. Warning:: It is possible to use this on macOS or other BSD-based systems, although GNU tools will need to be installed; it is also recommended to install the RISC-V toolchain from ``brew``.
.. Warning:: Working under Windows is not recommended.
Setting up the Chipyard Repo
-------------------------------------------
Start by fetching Chipyard's sources. Run:
.. code-block:: shell
git clone https://github.com/ucb-bar/chipyard.git
cd chipyard
./scripts/init-submodules-no-riscv-tools.sh
This will initialize and checkout all of the necessary git submodules.
Installing Dependencies
-------------------------------------------
Installing the recommended dependencies on Ubuntu/Debian-based platforms:
.. code-block:: shell
./scripts/ubuntu-req.sh
Installing the recommended dependencies on CentOS-based platforms:
.. code-block:: shell
./scripts/centos-req.sh
Installing the RISC-V Tools
-------------------------------------------
We need to install the RISC-V toolchain in order to be able to run RISC-V programs using the Chipyard infrastructure.
This will take about 20-30 minutes. You can expedite the process by setting a ``make`` environment variable to use parallel cores: ``export MAKEFLAGS=-j8``.
To build the toolchains, you should run:
.. code-block:: shell
./scripts/build-toolchains.sh
.. Note:: If you are planning to use the Hwacha vector unit, or other RoCC-based accelerators, you should build the esp-tools toolchain by adding the ``esp-tools`` argument to the script above.
If you are running on an Amazon Web Services EC2 instance, intending to use FireSim, you can also use the ``--ec2fast`` flag for an expedited installation of a pre-compiled toolchain.
Finally, set up Chipyard's environment variables and put the newly built toolchain on your path:
.. code-block:: shell
source ./env.sh
What's Next?
-------------------------------------------
This depends on what you are planning to do with Chipyard.
* If you intend to run a simulation of one of the vanilla Chipyard examples, go to :ref:`sw-rtl-sim-intro` and follow the instructions.
* If you intend to run a simulation of a custom Chipyard SoC Configuration, go to :ref:`Simulating A Custom Project` and follow the instructions.
* If you intend to run a full-system FireSim simulation, go to :ref:`firesim-sim-intro` and follow the instructions.
* If you intend to add a new accelerator, go to :ref:`customization` and follow the instructions.
* If you want to learn about the structure of Chipyard, go to :ref:`chipyard-components`.
* If you intend to change the generators (BOOM, Rocket, etc) themselves, see :ref:`generator-index`.
* If you intend to run a tutorial VLSI flow using one of the Chipyard examples, go to :ref:`tutorial` and follow the instructions.
* If you intend to build a chip using one of the vanilla Chipyard examples, go to :ref:`build-a-chip` and follow the instructions.
