Class BlockPlacer

Object

com.xilinx.rapidwright.placer.blockplacer.AbstractBlockPlacer<HardMacro,Site>

com.xilinx.rapidwright.placer.blockplacer.BlockPlacer

public class BlockPlacer
extends AbstractBlockPlacer<HardMacro,Site>

Initial attempt at a pre-implemented module placer. It is more accurate in that it tries to traverse critical paths into both ends of the connections made between hard macros.
