Guide – How to: setup DPR environment

Latest update: 2023-04-11

This guide provides the installation and setup for the Gurobi optimizer that enables to design partially reconfigurable SoCs in ESP.

Gurobi Installation

ESP uses the Gurobi optimizer (with an academic license) to automate the floorplanning stage of a DPR design for Xilinx FPGAs. The ESP dynamic partial reconfiguration (DPR) flow is tested with Gurobi version 8.1.1. We will soon support newer versions of the optimizer.

In order to install Gurobi, please login or create account Create an account.

Once the installation is complete

mkdir <gurobi_install_path>
cd <gurobi_install_path>

# Download Gurobi optimizer
wget https://packages.gurobi.com/8.1/gurobi8.1.1_linux64.tar.gz
tar xvf gurobi8.1.1_linux64.tar.gz

# create a soft link to /usr/lib
sudo ln -s <gurobi_install_path>/gurobi811/linux64/lib/libgurobi81.so /usr/lib/
sudo ln -s <gurobi_install_path>/gurobi811/linux64/lib/libgurobi_g++4.2.a /usr/lib/
sudo ln -s <gurobi_install_path>/gurobi811/linux64/lib/libgurobi_g++5.2.a /usr/lib/
sudo ln -s <gurobi_install_path>/gurobi811/linux64/lib/libgurobi_c++.a /usr/lib/

Gurobi Academic License

After the installation, obtain an unlimited use Named-User Academic license from here.

Note: You can also generate other types of licenses as long as they support the version of Gurobi used in ESP.

Once the license_code is generated run

<gurobi_install_path>/gurobi811/linux64/bin/grbgetkey  license_code
