PyMTL 3 (Mamba)



PyMTL 3 (Mamba) is the latest version of PyMTL, an open-source
Python-based hardware generation, simulation, and verification framework with
multi-level hardware modeling support. The original PyMTL was introduced
at MICRO-47 in December, 2014. Please note that PyMTL 3 is currently
beta software that is under active development and documentation is
currently quite sparse.
In June 2019, Keeping Computer Hardware Fast and Furious: "PyMTL is a fantastic example of what we need to jump-start the open-source hardware ecosystem…It’s a key missing link." was featured on Cornell Research.
User Forum
We recommend the user to post on https://groups.google.com/forum/#!forum/pymtl-users to ask questions about using PyMTL 3. The github issues are reserved for development purposes, e.g., bug reports and feature requests.

Installation
The steps for installing these prerequisites and PyMTL on a fresh Ubuntu
distribution are shown below. They have been tested with Ubuntu Xenial 18.04.
Install PyMTL 3
tl; dr pip install pymtl3

PyMTL 3 requires Python 3.6+. We highly recommend you work inside a virtual environment instead of calling sudo pip install. Starting from Python 3.5, the use of venv is now recommended for creating virtual environments.
$ cd <path to where venvs are stored>
$ python3 -m venv pymtl3 # you can use whatever Python 3.6+ binary you have
$ source pymtl3/bin/activate

PyMTL 3 needs to use cffi, so install these packages first.
$ sudo apt-get install git python-dev libffi-dev

PyMTL 3 is available on pypi.org. As a result, you are able to just call pip install pymtl3 to install PyMTL 3.
$ pip install pymtl3

When you relaunch the bash session, you need to re-enable the venv.
$ source <path to where venvs are stored>/pymtl3/bin/activate

When you're done testing/developing but you don't want to close the terminal, you can deactivate the virtualenv:
$ deactivate

Additional dependencies include verilator(and pkg-config) when you want to integrate SystemVerilog blackbox into your PyMTL simulation.
Install Verilator
Verilator is an open-source toolchain for compiling SystemVerilog RTL
models into C++ simulators. You can install Verilator using the
standard package manager but the version available in the package
repositories is several years old. This means you will need to build and
install Verilator from source using the following commands:
$ sudo apt-get install git make autoconf g++ libfl-dev bison
$ mkdir -p ${HOME}/src
$ cd ${HOME}/src
$ wget http://www.veripool.org/ftp/verilator-4.036.tgz
$ tar -xzvf verilator-4.036.tgz
$ cd verilator-4.036
$ ./configure
$ make
$ sudo make install

Verify that Verilator is on your path as follows:
$ cd $HOME
$ which verilator
$ verilator --version

PyMTL uses pkg-config to find the Verilator source files when
integrating SystemVerilog blackbox. Install
pkg-config and verify that it is setup correctly as follows:
$ sudo apt-get install pkg-config
$ pkg-config --print-variables verilator

If pkg-config cannot find information about verilator, then you can
also explicitly set the following special environment variable:
$ export PYMTL_VERILATOR_INCLUDE_DIR="/usr/local/share/verilator/include"
