I designed and developed a heuristic algorithm to place components on PCB layout. I designed the layout first by KiCAD, an open source PCB design software from CERN, that generates netlist and PCB files. My placer reads these two files and runs the algorithm to place components in optimal way and to reduce the total wire length.
