Here is some information on downloading the placement and routing
tools. You can (and should) make use of this available infrastructure
for the project. The first set of tools that you want to download is
the Michigan Physical Design toolset from Igor's website, which are
mostly for floorplanning and placement. Next, you can also obtain
FastRoute and FLUTE related sources from Prof. Chris Chu's website. 

1. Get UMPack:

http://vlsicad.eecs.umich.edu/BK/PDtools/

Follow the instructions for configure and compilation. It compiles
alright on the CADE lab machines, even though with a million
warnings. Unfortunately, MAC OS (Darwin!!) is not supported, probably
due to hMetis-related issues.

Go to the UMPack-xxxxx/Capo/TEST directory, and look at the *.aux,
*.nodes, *.net, *.pl files. These file formats are based on the
bookshelf format. A description of the benchmark format 
http://vlsicad.eecs.umich.edu/BK/ISPD06bench/BookshelfFormat.txt

Once all the sources are compiled, the executables are located in the
directory ./UMPack-xxxxx/bin

Since we are mostly concerned with floorplanning and placement, the
executable of interest is MetaPl-Capo10.5-Lnx32.exe, which is the
basic floorplacer.

Go to ./UMPack-xxxx/Capo/TEST/ and run the placement on the *.aux
files. E.g., run

../../bin/MetaPl-Capo10.5-Lnx32.exe -f C432a.aux -save -plot plot

and the final placement is produced in 'out.pl' file and a gnuplot
format file plot.plt is also produced which can be viewed and PDF
printed. 

Those of you who are doing your own placement/floorplanning based
projects, try to use whatever sources you can from here, and see if
you can build your project in a similar fashion.

2. Regarding the routing tools:

Go to http://home.eng.iastate.edu/~cnchu/FastRoute.html

and fill up the request for the source code. They have requested that
whoever wants to use FastRoute and FLUTE, should file an individual
request. The source compiles easily and runs fine. 

Those of you who are working on routing, can use the flute.c source
files and obtain HPWL and FLUTE wirelength estimates using these
sources. [BTW, UMPack also uses the FLUTE package].

FastRoute uses the ISPD 2008 contest benchmark format for the global
routing, which is similar to the bookshelf one, but probably more
unified. See
