NAME


graywolf - placement tool for digital VLSI design

SYNOPSIS


graywolf [options] designName [windowId] [flowdirectory]

DESCRIPTION


This is a utility used to perform placement of digital VLSI designs. It is based on some
code from the early 90s and it is one of the building blocks of the open source qflow
digital design flow.

OPTIONS


-n no graphics

-d prints debug info and performs extensive error checking

-g general mode

-p pick mode

-w parasite mode will inherit a window

USAGE


Typically, you would be in a directory with a [DESIGN].cel file and a [DESIGN].par file
and then run:

graywolf [DESIGN]

where [DESIGN] is the file name of the design. More information about the input and output
files is found below.

However, it is recommended to use the qflow digital design flow instead of running
graywolf directly. qflow prepares the input files from standardized files, and converts
the output to standardized files.

INPUT


Two input files are necessary to run graywolf. A .cel file containing the design, and a
.par file containing the parameters which define the technology. The .cel file may be
created from a .blif design file and a .lef library file with the script "blif2cel.tcl" in
the qflow package.

OUTPUT


The main output from graywolf is a .pl1 file containing the layout of the design. This may
be converted to a .def file using the script "place2def.tcl" in the qflow package. A .def
file is a standardized description of a layout.
