-
Navigate to the directory where you have the input files.
-
Run RePlAce container:
docker run -it -v $(pwd):/data openroad/replace bash -
From the interactive bash terminal, use RePlAce scripts which reside under
/RePlAce. You can read input files from/datadirectory inside the docker container - which mirrors the host machine directory you are in.
- The Docker image is self-contained and includes everything that RePlAce needs to work properly.
- Intel MKL packages Link >= 2016.3.210
- GCC compiler and libstdc++ static library >= 4.8.5
- boost library >= 1.41
- bison (for lef/def parsers) >= 3.0.4
- tcl (for OpenSTA) >= 8.4
- X11 library (for CImg library to visualize) >= 1.6.5
- Recommended OS: Centos6, Centos7 or Ubuntu 16.04
$ git clone --recursive https://github.com/abk-openroad/RePlAce.git
$ cd ~/RePlAce
$ ./prerequisite/install_centos7.sh // for centos 7
$ ./prerequisite/install_ubuntu16.sh // for ubuntu 16
$ mkdir build
$ cd build
$ cmake .. // you may specify -DCMAKE_INSTALL_PREFIX to avoid installing in /usr/local/*
$ make
$ make install
To make sure your installation is correct and the current tool version is stable enough,
run a Hello World application:
$ cd ./test
$ ./run.sh
// download lefdef benchmarks
$ cd ~/RePlAce/bench/ispd18
$ ./download_ispd18.sh
// Generate a result from ISPD18 - ispd18.test1.input
// Check doc/ScriptUsage.md in detail
$ cd ~/RePlAce/src
$ ./execute_lefdef.py 0

- Timing-Driven mode has been implemented by Mingyu Woo.
- Mixed-sized RePlAce with (LEF/DEF/Verilog) interface does not generate legalized placement.
- RePlAce does not support rectilinear layout regions.
