SYNOPSIS¶

DESCRIPTION¶
This manual page documents briefly the
qrouter command.
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.
