.TH QROUTER 1 "April 28, 2014"
.SH NAME
qrouter \- Multi-level, over-the-cell maze router
.SH SYNOPSIS
.B qrouter
.RI [ options ] " design_name"
.br
.SH DESCRIPTION
This manual page documents briefly the
.B qrouter
command.
.PP
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.
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
