Extra info and code examples

Qrouter is a tool to generate metal layers and vias to physically connect together a netlist in a VLSI fabrication technology. It is a maze router, otherwise known as an "over-the-cell" router or "sea-of-gates" router. That is, unlike a channel router, it begins with a description of placed standard cells, usually packed together at minimum spacing, and places metal routes over the standard cells. Qrouter uses the open standard LEF and DEF formats as file input and output. It takes the cell definitions from a LEF file, and analyzes the geometry for each cell to determine contact points and route obstructions. It then reads the cell placement, pin placement, and netlist from a DEF file, performs the detailed route, and writes an annotated DEF file as output.
