Installation Instructions
In order to install the PandA framework, you need to perform the following steps:
1) Give write permission to your user on /opt:
$chown -R <username.usergroup> /opt
2) Install required packages (for Ubuntu/Debian/CentOS/Scientific Linux/ArchLinux/Fedora systems, see below)
3) Prepare the configuration script:
$make -f Makefile.init
4) Create the directory for the building:
$mkdir obj $cd obj
5) Configure PandA:
$../configure [--enable-<ext-feature>...] --prefix=/opt/panda
The complete list of options can be found by running:
$../configure --help
The most relevant ones are:
--enable-flopoco: add floating point support by leveraging FloPoCo Library
http://flopoco.gforge.inria.fr/
--enable-debug: add debugging symbols to the binaries
--enable-opt: compile the framework with GCC optimizations enabled
--enable-release: remove further tests not useful in a production environment
--enable-glpk: enable the GNU Linear Programming Kit, required for SDC scheduling
--with-compiler: set a non-standard path to the executable of a compiler
(gcc45 - gcc8 and clang4 - clang13)
--with-prefix: install folder
Note: since FloPoCo generates a VHDL-based description, co-simulation requires a mixed-language simulator. Both Modelsim from Mentor and XSIM/ISIM from Xilinx have such support.
7) Compile the tool:
$make
8) Install the tool:
$make install
At the end, if the installation has been successful, you can run the tool:
$/opt/panda/bin/bambu
which prints its help message.
Additional documentation about the configuration, the execution of the test examples, and the creation of the basic documentation of the framework can be found at: http://panda.dei.polimi.it/?page_id=88
Testcases
In the directory examples, you can find several different testcases, with the bash scripts for their execution.
These scripts automatically create subdirectories containing all the results of the execution. You can start from them to build your own hardware accelerators with bambu.
Documentation
After configuring the framework in the directory for the building, you can create a preliminary documentation of the framework by executing the following
command:
$cd obj $make documentation
Then, you can start browsing the documentation from the file
obj/doc/PANDA_html/index.html

CentOS 6/Scientific Linux distributions
These two distributions are very similar and present the very same problems. They use an old gcc compiler, not compatible with the PandA framework and they do not have a compatible version of boost libraries. So these are few notes for those who are still willing to install the PandA framework on such systems.
First, some dependencies need to be satisfied:
$ sudo yum install python-devel zlib-devel bzip2-devel libicu-devel glibc-devel.i686 libgcc.i686 wget tar bzip2 gcc glibc-devel gcc-c++ suiteparse-devel libtool-ltdl-devel glpk-devel
autoconf-archive package is also required, but it is not present in CentOS repositories:
$ wget ftp://ftp.pbone.net/mirror/ftp5.gwdg.de/pub/opensuse/repositories/home:/pelliott11:/autoconf-archive/CentOS_CentOS-6/noarch/autoconf-archive-2012.04.07-7.3.noarch.rpm $sudo rpm -Uvh autoconf-archive-2012.04.07-7.3.noarch.rpm
Then a recent version of boost has to be installed by hand.
$ wget http://sourceforge.net/projects/boost/files/boost/1.48.0/boost_1_48_0.tar.bz2/download $ cp download boost_1_48_0.tar.bz2 $ tar xf boost_1_48_0.tar.bz2 -C /tmp $ cd /tmp/boost_1_48_0/ $ sudo mkdir -p /opt/boost/1.48.0 $ sudo ./bootstrap.sh $ sudo ./bjam --prefix=/opt/boost/1.48.0/ variant=release install
Once you have boost installed, you need a recent gcc to compile the PandA sources. This can be done with devtools
On CentOS you can retrieve the devtools repos with the following line:
$ sudo wget http://people.centos.org/tru/devtools-1.1/devtools-1.1.repo -O /etc/yum.repos.d/devtools-1.1.repo
On Scientific Linux you can follow the instructions at this link http://linux.web.cern.ch/linux/devtoolset/ to retrieve the repos info.
Then for gcc-4.7.2 run the following line:
$ sudo yum install devtoolset-1.1 devtoolset-1.1-runtime devtoolset-1.1-binutils devtoolset-1.1-binutils-devel devtoolset-1.1-build devtoolset-1.1-dwz devtoolset-1.1-elfutils devtoolset-1.1-elfutils-devel devtoolset-1.1-elfutils-libelf devtoolset-1.1-elfutils-libelf-devel devtoolset-1.1-elfutils-libs devtoolset-1.1-gcc devtoolset-1.1-gcc-c++ devtoolset-1.1-gcc-gfortran devtoolset-1.1-gcc-plugin-devel devtoolset-1.1-gdb devtoolset-1.1-libitm-devel devtoolset-1.1-libquadmath-devel devtoolset-1.1-libstdc++-devel devtoolset-1.1-valgrind
After this you can enable gcc-4-7 by typing:
$ scl enable devtoolset-1.1 bash
Finally, the following packages have to be installed:
$ sudo yum install automake bison flex libtool libxml2-devel mpfr-devel
This environment allows the compilation of the PandA framework with a minimal configuration without flopoco library and without Icarus verilog simulator.
The configure we tested for centos is the following one:
$ CXX=/opt/centos/devtoolset-1.1/root/usr/bin/g++ CC=/opt/centos/devtoolset-1.1/root/usr/bin/gcc ../configure --prefix=/opt/panda --enable-opt --enable-release --with-boost=/opt/boost/1.48.0/ --with-gcc47=/opt/centos/devtoolset-1.1/root/usr/bin/gcc
where –with-boost specifies the manually installed boost library and –with-gcc47 specifies the gcc executable provided by devtools-1.1.
FloPoCo is currently not supported by bambu under CentOS 6.
Note that, before the configure, you need to run the make -f Makefile.init command as described in the standard PandA *Installation Instructions*.
CentOS 7
The following packages have to be installed under Centos 7 to compile PandA:
- autoconf - autoconf-archive - automake - bison - boost-devel - flex - gcc-c++ - gcc-plugin-devel - glibc-devel.i686 - glpk-devel - libgcc.i686 - libicu-devel - libtool - libtool-ltdl-devel - libxml2-devel - make - mpfr-devel - suitesparse-static - verilator - xz-devel - zlib-devel
Extra packages for Enterprise Linux (EPEL) is required:
yum install epel-release
In a single line (as root):
yum install autoconf autoconf-archive automake bison boost-devel flex gcc-c++ gcc-plugin-devel glibc-devel.i686 glpk-devel libgcc.i686 libicu-devel libtool libtool-ltdl-devel libxml2-devel make mpfr-devel suitesparse-static xz-devel zlib-devel
FloPoCo is currently not supported by bambu under CentOS 7.

ArchLinux
The following packages have to be installed under ArchLinux to compile PandA:
- base-devel - multilib-devel - boost - iverilog - gcc-multilib - autoconf-archive - verilator - mpfi - clang - llvm - gcc - gcc-fortran - git - tar - suitesparse - glpk - readline
In a single line:
sudo pacman -S base-devel multilib-devel boost iverilog gcc-multilib autoconf-archive verilator mpfi clang llvm gcc gcc-fortran git tar suitesparse glpk readline
A working configure example is:
../configure --prefix=$HOME/panda --enable-verilator --enable-glpk --enable-opt --enable-flopoco --with-opt-level=fast
Mac OSX
To compile PandA on MacOSX you need to install MacPorts (version 2.5.4 or later).
Here the list of commands required:
$sudo port -N -q install git autoconf autoconf-archive automake bison flex boost libtool SuiteSparse glpk iverilog clang-6.0 gcc8 mpfi coreutils
$sudo cp /opt/local/bin/greadlink /opt/local/bin/readlink
$git clone https://github.com/ferrandi/PandA-bambu.git
$cd PandA-bambu
$make -f Makefile.init
$mkdir build
$cd build && ../configure --prefix=$HOME/panda --enable-icarus --enable-glpk --enable-opt --enable-flopoco --with-opt-level=fast --with-clang6=/opt/local/bin/clang-mp-6.0 --with-gcc8=/opt/local/bin/gcc-mp-8 LDFLAGS=-L/opt/local/lib CPPFLAGS=-I/opt/local/include/ && make -j3 && make install && make clean
Notes on Ubuntu 13.04 64bit and XILINX ISE 14.6
The vendor version of stdlibc++ does not have the correct versions of GLIBC for Ubuntu 13.04.
This is probably due to the fact that the tool is loading a mixture of system libraries and vendor libraries.
The solution is to replace the Xilinx version of stdlibc++ with the system version:
In case ISE is installed in /opt/Xilinx/14.6/ the solution is:
$cd /opt/Xilinx/14.6/ISE_DS/ISE/lib/lin64/ $sudo mv libstdc++.so.6 libstdc++.so.6.orig $sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6
Notes on Debian/Ubuntu and Lattice Diamond 3.9
Lattice Diamond is currently distributed in rpm form for Linux distributions. To convert an rpm archive file into a .deb you can use the following instructions:
$sudo apt-get install alien $sudo alien --scripts diamond_3_9-base_x64-99-2-x86_64-linux.rpm
once the package has been converted you can install with:
$sudo dpkg -i diamond-3-9-base-x64_3.9-100_amd64.deb
Notes on NanoXplore tools
The tested version of NanoXplore tools is the 2.9.4.
The configuration of the PandA framework may require to add this option to the configure script:
–with-nanoxplore-bypass=<operating-system-distribution>
where possible value can be:
x86_64_UBUNTU_14
x86_64_UBUNTU_16
x86_64_UBUNTU_18
x86_64_DEBIAN_9
x86_64_RHEL_6
Notes on Modelsim
PandA/bambu supports both Modelsim full version and Student/Free version by adding –enable-modelsim option to the PandA configure.
When the Free/Student version of Modelsim is used, PandA/bambu should be configured by further adding the –disable-mentor-optimizer option. The Student/Free version does not have the optimization feature.
Notes on backend installation directories
PandA/bambu automatically looks for the RTL synthesis/simulation backends once they are enabled. By default, it looks into specific directories of the filesystem.
For Altera it checks this set of directories /opt/altera/* /opt/intelFPGA/*
For Lattice it checks this set of directories /usr/local/diamond/*
For Mentor it checks this set of directories /opt/mentor and /opt/mentor/*
For Xilinx ISE it checks these sets of directories /opt/Xilinx/* and /opt/Xilinx/*/ISE*
For Xilinx VIVADO it checks this set of directories /opt/Xilinx/* and /opt/Xilinx/Vivado/*
For BRAVE FPGA NanoXplore it checks this set of directories /opt/NanoXplore/NXmap/*
Anyway, it is possible to specify a different position of the filesystem for the configuration script to look into.
This is the list of options that may be useful for this purpose:
--with-altera-dir=DIR where the root where ALTERA tools are installed --with-lattice-dir=DIR where the root where LATTICE tools are installed --with-mentor-dir=DIR where the root where MENTOR tools are installed --with-xilinx-root-dir=DIR where the root where XILINX tools are installed
