The XLS (Accelerator Synthesis) toolchain aims to enable the rapid development of hardware IP via "software style" methodology. XLS is a High Level Synthesis (HLS) toolchain which produces synthesizable designs from flexible, high-level descriptions of functionality.
Currently, XLS must be built from source using the Bazel build system.
The following instructions are for the Ubuntu 20.04 (Focal) Linux distribution:
# Follow the bazel install instructions:
# https://docs.bazel.build/versions/master/install-ubuntu.html
#
# Afterwards we observe:
$ bazel --version
bazel 3.2.0
$ sudo apt install python3-dev python3-distutils python3-dev libtinfo5
# py_binary currently assume they can refer to /usr/bin/env python
# even though Ubuntu 20.04 has no `python`, only `python3`.
# See https://github.com/bazelbuild/bazel/issues/8685
$ mkdir -p $HOME/opt/bin/
$ ln -s $(which python3) $HOME/opt/bin/python
$ echo 'export PATH=$HOME/opt/bin:$PATH' >> ~/.bashrc
$ source ~/.bashrc
$ bazel test -c opt ...
