Program that generates FPGA architectures using Genetic Algorithm. In the current implementation, K (number of inputs to a LUT), N (number of LUTs in a cluster), and W (channel width) are varied to find the optimal combination for a given set of benchmarks. Combinations of parameters are evaluated using VTR.
- C++ compiler that supports C++11 standards
- VTR
- GNU/Linux or Unix-like operating system that uses
/as the path separator - CMake 2.8 or later
When compiling with debug on (i.e. with -DCMAKE_BUILD_TYPE=Debug)
- Boost.Test framework
- C++ compiler that has support for OpenMP
Clone this repository and go to the top-level directory. Assuming VTR is
installed in ~/src/vtr-verilog-to-routing, the program can be run with:
$ cd ./build
$ cmake ..
$ export OMP_NUM_THREADS=8
$ ./src/fp-GA-architecture ~/src/vtr-verilog-to-routing /path/to/benchmark/file
Various parameters for the genetic algorithm are described in the help
message, which is displayed when the program is invoked with the -h or
--help command line option.
This program was developed and checked on a gluster file system. There seems
to be an
issue
where directories cannot be removed. Thus, after running the program, there
may be directories that are formatted as NUM1_NUM2_NUM3. You can remove
these directories once the program has finished.
