Overview

ZynqParrot enables rapid design iteration of Accelerators (including the BlackParrot RISC-V processor) on Zynq FPGAs.

See The ZynqParrot Co-simulation Development Flow for the architecture of the BSG ZynqParrot shell and how it is integrated with BlackParrot.

ZynqParrot Repository Overview

Prerequisites

CentOS 7+

To install most dependencies, execute the following command:

sudo yum install autoconf automake bash bc binutils bison bzip2 cpio dtc expat-devel file flex gawk gcc gcc-c++ git gmp-devel gzip gtkwave java-1.8.0-openjdk-headless libmpc-devel libuuid-devel make mpfr-devel patch patchutils perl perl-ExtUtils-MakeMaker python3 python3-pip rsync sed tar tcl texinfo unzip vim-common virtualenv which zlib-devel

On CentOS 7, some tools provided by the base repository are too old to satisfy the requirements. We suggest using the Software Collections (SCL) to obtain newer versions.

sudo yum install centos-release-scl scl-utils
sudo yum install devtoolset-9 rh-git218
scl enable devtoolset-9 rh-git218 bash

To automatically enable these tools from SCL on new terminals, add the following line to ~/.bashrc:

source scl_source enable devtoolset-9 rh-git218

Moreover, the cmake package on CentOS 7 is CMake 2 while we need CMake 3. We suggest installing CMake 3 from EPEL:

sudo yum install epel-release
sudo yum install cmake3

On CentOS 8 and later, the cmake package is CMake 3 and works well without CMAKE=cmake3:

sudo yum install cmake

Ubuntu

sudo apt-get install autoconf automake autotools-dev cmake curl default-jre libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev wget byacc device-tree-compiler python gtkwave uuid-dev vim-common virtualenv python-yaml

We need the orderedmultidict Python package too, but it is not packaged by default. Installing it from PyPI works:

pip install --user orderedmultidict

BlackParrot has been tested extensively on CentOS 7. We have many users who have used Ubuntu for development. If not on a relatively recent version of these OSes, we suggest using a Docker image.

Build the toolchains

# Clone the latest repo
git clone https://github.com/black-parrot-hdk/zynq-parrot.git
cd zynq-parrot

# make checkout will checkout submodules needed for all of the examples. Users who just want
#   to try out simple examples and not a full RISC-V program need only run this as preparation
make checkout

# make prep is a meta-target which will build the RISC-V toolchains, programs and microcode
#   needed for a full BlackParrot evaluation setup.
# Users who are changing code can use the targets in tagged submodules as appropriate
# For faster builds, make prep -j is parallelizable!
# To get started as fast as possible, use 'make prep_lite' which installs a minimal set of tools
# BSG users should instead use 'make prep_bsg', which sets up the bsg CAD environment
make prep

See cosim directory for a list of cosimulation examples.
