A quadratic placer for placements of chips with less than 100000 gates. Can be extended to a higher number of gates as well. The ASIC has been assumed to have x-coordinate from 0 to 100, and y-coordinate from 0-100.
Build the project using the Makefile provided. An optional input is the value of N. It decides the number of recursions that the placer need to take. If N = 10, it means that the gates need to be distributed into 2^10 basic cells of equal area.
make build or make build N=10
The executable needs an input file in a specific format. Some input files are presented in the folder named "benchmarks". Use one of these input files to run.
./qplacer ./benchmarks/industry1
The final placement is written back to an output file. The output can be visualized using a python script. Use the Makefile for the same.

- C++11 std library: Use
-std=c++11flag while using g++.
- Python 2: Python 2 is mostly preinstalled in linux systems.
- pyplot: pyplot is present in the python library matplotlib. Install
python-matplotlibin your machine.
