### Pre-requisite
- [GCC](https://gcc.gnu.org)
- Recommend GCC 4.8 or later.
- Other compilers may also work, but not tested.
- [CMake](https://cmake.org)
- Require 3.8.2 or later.
- [Boost](https://www.boost.org)
- Require 1.55...1.72.
- Need to install and visible for linking.
- Custom installation path may require to export ```BOOST_ROOT``` for [CMake](https://cmake.org/cmake/help/v3.8/module/FindBoost.html).
- [Limbo](https://github.com/limbo018/Limbo)
- Integrated as a git submodule.
- [Gurobi](https://www.gurobi.com) (Optional)
- ILP solver.

### Docker Version
We provide the docker version to avoid annoying compilation.
You can pull the image by
```bash
$ docker pull wadmes/openmpl:latest
```
The OpenMPL folder locates in `/home/OpenMPL`
### How To Compile
```bash
$ git clone https://github.com/limbo018/OpenMPL.git
$ cd OpenMPL
$ git submodule update --init --recursive
$ mkdir build
$ cd build
$ cmake ..
$ make
$ make install
```
The default installation path is the repo directory. It can be changed via
```
cmake .. -DCMAKE_INSTALL_PREFIX=your_installation_path
```
### Features
* Contact or metal layer decomposition
* Stitching
* Support 3 or 4 coloring
* Density control
* Multi-threading
* Small memory usage
* Multiple algorithms:
* ILP (Gurobi API)
* SDP (Csdp API)
* LP (Gurobi API)
* Dancing Links
The Csdp API used in OpenMPL has been modified and built for threading safety at high level.
### How to Get Benchmarks
Small benchmarks (ISCAS) [Download](https://yuzhema.people.ust.hk/release/ISCAS_benchmark.zip)
big benchmarks (ISPD19) [Download](https://yuzhema.people.ust.hk/release/ISPD19.zip)
### How To Execute
```bash
$ cd bin/
$ ./OpenMPL
```
A table of options :
```bash
-help (false) toggle printing help message
-in input gds file name
-out () output gds file name
-coloring_distance (0) a floating point number indicating number of coloring distance in nanometer
-color_num an integer indicating number of masks (colors) < 3|4 >
-simplify_level (3) an integer indicating graph simplification level < 0|1|2|3 >
-thread_num (1) an integer indicating maximum thread number
-path_layer an integer indicating layer for conflict edges
-precolor_layer an integer indicating layer for pre-colored patterns
-uncolor_layer an integer indicating layer for coloring
-algo (BACKTRACK) algorithm type < ILP|BACKTRACK|LP|SDP >
-shape (RECTANGLE) shape mode < RECTANGLE|POLYGON >
-verbose (false) toggle controlling screen messages
-dbg_comp_id (4294967295) debug component id
-use_stitch use stitch to avoid conflict
-gen_stitch generate stitch candidate
-weight_stitch a floating point number indicating the weight of stitch
```
One exmaple : /bin/run.sh.
Another example for large benchmark: /bin/run_big.sh
### Possible Compiler Problems
+ default CFLAGS of boost and gurobi are different in newest version
+ downgrade the boost version
+ ```
SimpleMPL.cpp:461:5: error: ‘graph_simplification_type’ has no member named ‘set_isVDDGND’
```
+ checkout to ***stitch*** branch in your limbo directory
