About:

Ophidian is an open-source library developed at Embedded Computing Lab (ECL), Federal University of Santa Catarina (UFSC), Brazil. The main objective of Ophidian project is to provide a multi-platform library to facilitate the research and teaching of topics associated to the physical design of integrated circuits.

Ophidian was conceived by Chrystian Guth, Renan Netto, and Vinicius Livramento, under the advise of Prof. José Güntzel, during their research activities at Federal University of Santa Catarina.

Getting Started!

Get Ophidian! We support a few of the most used linux environments.

Debian Family:

Add the Ophidian repository ppa.

Ubuntu artful (17.10) or newer:

$ sudo add-apt-repository -y -u ppa:eclufsc/ophidian
$ sudo apt install libophidian-dev

Debian buster (10) or newer:

First you will need to add the Launchpad PPA for eclufsc gpg key:

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A62C1A5EFCB3D41A1FDB35758179B53998C15E64 && apt-get update -qq

Then add the launchpad repository and install ophidian.

$ sudo add-apt-repository -y -u -m "deb http://ppa.launchpad.net/eclufsc/ophidian/ubuntu artful main"
$ sudo apt install libophidian-dev

Arch Linux:

Just install it via the AUR package ophidian-git:

$ pacaur -S ophidian-git

Others:

If we do not support your distro, consider building it from source!

Hello World!

So you want to code? We make avaliable a project template to make your life easier!

So you want to push new code to Ophidian? First you should have an idea of the project structure:

The main ophidian/CMakeLists.txt file:

This is the main Cmake file for the ophidian project, it's goals are set up project variables, handle dependencies and include the project subdirectories.

The ophidian/build_dependencies.sh script:

This script serves as a c++ npm, gem, pip, equivalent. It will fetch all third party git submodules located at ophidian/3rdparty, compile and install them to ophidian/dependencies by default.

The ophidian/cmake directory:

Here you will have all custom made cmake modules used by the CMakeLists.txt files.

The ophidian/3rdparty directory:

This directory holds the git submodules with the source code of ophidian's dependencies.

The ophidian/ophidian directory:

Here you will have directories for each library developed by the ophidian team. Each library directory will have its own CMakeLists.txt file with its own compilation instructions.

The ophidian/ophidian/CMakeLists.txt file:

This file handles the installation rules for the ophidian library.

The ophidian/test directory:

Here you will find directories for each ophidian library unit tests.

The ophidian/test/CMakeLists.txt file:

This file handles the compilation instructions for the unit tests binary.

Build and Installation Guide:

This section will guide you on the compilation process of the Ophidian library. The Ophidian library depends on the following third party software:

Dependencies:

• Cmake (>= 3.5.2)
• Boost (>= 1.63)
• Lemmon
• Units
• Flute
• Verilog-Parser
• DEF
• LEF

Although some of this dependencies like Cmake and Boost are realy well supported on any operational system, the others can be a hassle to have on your system. So you can try building them yourself!

Build Dependencies:

First make shure you have all dependencies dependencies:

Dependencies Dependencies:

• zlib
• Bison
• Flex

Using the build_dependencies.sh script:

Run the provided script build_dependencies.sh located at the source root.

$ bash build_dependencies.sh

Compiling Ophidian:

Ophidian uses Cmake as a build system generator, if you are familiar with it you probably know the following:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

Cmake Configuration options:

-DOPHIDIAN_TESTS_FULLY_STATIC=ON will staticly link libc and libc++.

-DUNCRUSTIFY_IT=ON will run uncrustify in all files.

-DUNCRUSTIFY_CHECK=ON will run check all files formating with uncrustify.

In order to run the ophidian unity tests, inside the build directory, execute the folowing:

cd test
./ophidian_tests

P.S. ophidian_tests needs to be executed from the test directory due to the inputfile's path being hardcoded.

[optional] Install Dependencies on System:

If you wish to install dependencies on your system run:

$ sudo bash build_dependencies.sh --install_to /usr/local

This will install all dependencies to the /usr/local directory.

[optional] Install Ophidian on System:

If you wish to install Ophidian on your system please make shure your have installed all dependencies on your system first then run:

 $ sudo make install

This will install the Ophidian Library to the /usr/local directory.
