PRWorkshop88 - From the International Workshop on Placement and
			Routing, May 1988, Research Triangle Park, NC.


There are two versions of the files for this benchmark set.  The data files
from version 1.0 are duplicated in version 2.0; except data file Test07.yal,
which has been changed in version 2.0.  In addition, there are new files
in version 2.0 which are not present in the earlier version.

		How To Obtain Benchmark Data

The Place and Route 1988 benchmark data can be obtained from CBL in one
of two ways: by FTP over Internet or by tape.

1.0 Internet FTP

If you have access to an Internet connection you may establish an FTP
connection to host "mcnc.org" and copy the files using the "get"
command.  The login name is "anonymous" and the password is any string
(we request that you use your e-mail address).

The files are in the "pub/benchmark/Benchmark_dirs/PRWorkshop88"
directory.  Tar files, and compressed tar files exist for both version
1.0 and 2.0.  Most users will only want to get version 2.0; however,
the examples below show the user how to get both sets.  Ignore any
command to get a file with a "1.0" in the name if you do not want
version 1.0.

The command sequence to establish a connection to the host machine is:

	ftp mcnc.org
	anonymous 	(in response to the "Name" prompt)
	(your id) 	(in response to the "password" prompt)

If you have a UNIX(tm) machine on the Internet, check to see if you
have the "uncompress" and "tar" commands available. Shipping the
benchmarks over in a compressed tar format is much faster than in
individual ASCII files.

	cd pub/benchmark/Benchmark_dirs/PRWorkshop88
	get PRWorkshop88.readme
	get PRWorkshop88.list
	binary
	get PRW88_v1.0.tar.Z
	get PRW88_v2.0.tar.Z
	bye

on your local machine, uncompress the file with the commands

	uncompress PRW88_v1.0.tar.Z
	uncompress PRW88_v2.0.tar.Z

un-tar the files with the commands

	tar xvf PRW88_v1.0.tar
	tar xvf PRW88_v2.0.tar



FOR NON-UNIX USERS:

If you do not have the "compress" and "tar" utilities available, you
will have to copy the files explicitly. The actual files are stored
under the directories "pr_bench_v1.0" and "pr_bench_v2.0".  In
addition, "pr_bench_v2.0" has the following sub-directories:

	DATA, DOCUMENTATION, PARSER, REFERENCES

In the following example, all of the files from both versions are
copied to the local machine.  Since the version 1.0 files and
documentation should be kept separate from the version 2.0 files, this
example uses the "! mkdir" command of ftp to re-create the original
directory structure on the local machine just before each new
sub-directory is copied with the "mget" command.

	!mkdir PRWorkshop88
	lcd PRWorkshop88
	cd pub/benchmark/Benchmark_dirs/PRWorkshop88
	get PRWorkshop88.readme
	get PRWorkshop88.list
	prompt			# Should turn prompting off.
	! mkdir pr_bench_v1.0	# make "pr_bench_v1.0" dir on local machine.
	lcd pr_bench_v1.0	# move to "bench" on local machine.
	cd pr_bench_v1.0	# move to "bench" on remote machine.
	mget *			# get files from remote to local "bench".
	!mkdir ../pr_bench_v2.0	# make "pr_bench_v2.0" on local.
	lcd ../pr_bench_v2.0	#  etc.
	cd ../pr_bench_v2.0
	mget *
	! mkdir DATA
	lcd DATA
	cd DATA
	mget *
	! mkdir ../DOCUMENTATION
	lcd ../DOCUMENTATION
	cd ../DOCUMENTATION
	mget *
	! mkdir ../PARSER
	lcd ../PARSER
	cd ../PARSER
	mget *
	! mkdir ../REFERENCES
	lcd ../REFERENCES
	cd ../REFERENCES
	mget *
	! mkdir ../floorplan
	lcd ../floorplan
	cd ../floorplan
	mget *
	bye
