NAME
qrouter - Multi-level, over-the-cell maze router
SYNOPSIS
qrouter [-noc] [-s scriptname] [options] [design_name]
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.
USAGE
Qrouter can run be run in several ways:
1. Interactive mode. If qrouter is started without any options, a tkcon window will be
opened with an interpreter where commands may be entered.
2. Normal batch mode. This mode is activated if a tcl script is given with the "-s"
option. It can be run with or without a graphical window. If "-noc" is given, no
graphical window will appear.
Run without graphical window:
qrouter -noc -s routescript.tcl
Run with a graphical window showing the layout while it is routing:
qrouter -s routescript.tcl
3. Compatibility mode with qrouter 1.1. This mode is activated if either of the options
"-c", "-v", "-i", "-p" or "-g" are given. This is a batch mode.
OPTIONS
-noc No console mode
-s <scriptname>
Run scriptname
COMPATIBILITY MODE
-c <file>
Configuration file name (if not route.cfg)
-v <level>
Verbose output level
-i <name>
Print route names and pitches and exit
-p <name>
Specify global power bus name
-g <name>
Specify global ground bus name
INPUT
The input files for qrouter is an unrouted or partly routed .def file containing the
layout and a .cfg file containing the tcl script used to do the routing. The .cfg file
also needs to specify a .lef file describing the technology.
OUTPUT
qrouter will output the fully routed .def file (if successful routing). This may then
later be converted to a GDSII file using tools such as magic.
