An open-source infrastructure for VLSI design automation tool set.

Software Architecture

Key components include:

  • Database - OpenEDI database, core module.
  • Parser - parse standard data format and import data to OpenEDI databade.
  • CommandManager - manage commands.
  • MessageManager - manage messages.
  • IOManager - High-performance file IO.
  • GUI - Graphic user interface

Building Dependency (Recommend)

  1. GCC 6.5.0

  2. Cmake 3.12.4

  3. Qt 5.9.7

  4. Python 3.6

    Recommend to use anaconda

  5. Google test

    • Integrated as a submodule
  6. Pybind11

    • Integrated as a submodule
  7. Boost 1.69

    • Must be found by CMake
    • Recommend to use anaconda to install the library by conda install -c anaconda boost
    • Then export BOOST_ROOT=/path/to/anaconda so that CMake can find boost
    • If Boost is installed with other approaches, you can export BOOST_ROOT to wherever it is installed
  8. Tcl 8.6.9

  9. Flex 2.5.37+

  10. Bison 3.0.4+

  11. Gperftools 2.7.90

  12. LZ4 1.9.2

  13. Zstd 1.4.5

  14. readline 6.2+

Fast deployment(Virtual machine image)

  • Download and unzip, then use the virtual machine software(Support VMware Workstations/VMware Player/Virtualbox) to import CentOS7Dev.ovf and start it.
Download url:
Verification code: moqr
  • Operating System Username:root, Password:toor.

  • Before checkout openedi code, Please source /opt/devtoolset/devtoolset.bash first.

  • The default configuration of the virtual machine is 4 cores and 8GB memory. If multi-threaded compilation is enabled (the number of threads is greater than 8) during the compilation process, it may cause insufficient resources. Please manually modify the hardware configuration of the virtual machine.


  1. Clone the repository with submodules.
git clone --recursive

Alternatively, you can clone the repository and the submodules in two steps.

git clone
cd open-edi
git submodule update --init
  1. Build the program with cmake.
mkdir build   # assume you are inside the root directory of the repository
cd build
cmake ..      # you may add -DCMAKE_INSTALL_PREFIX=your/install/path to specify the location
make          # you may add -j to turn on parallel building
make test     # optional step to run unittests
make docs     # optional step to generate HTML documentations
make install


  1. Once installed (after make install), you can find the 'openEDA' binary under your/install/path/bin/ directory.

Invoke the binary, try

openEDA> read_lef test.lef

openEDA> read_verilog test.v

openEDA> read_def test.def

openEDA> read_timing_library test.lib
