Welcome to the ACG package version 1.0! Copyright (c) 2004-2008 Northwestern University. NuCAD Group. See COPYING for detailed license information. 1 INTRODUCTION This is a package for solving floorplanning problems using ACG family of representations. Two of them are included: a. non-Redundant Constraint Graph - Zhou et al., ICCD '04 b. ACG/Reduced ACG - Wang et al., ASPDAC '05 - Gu et al., DAC '05 A floorplanning framework is also provided but you have the freedom to only use the representations. 2 DIRECTORIES .: Information and demo. ./acg: Representations. ./fplan: The floorplanning framework. ./gsrc: GSRC benchmarks handling. ./misc: Supporting library. ./viewer: A viewer that displays the floorplan. You need ./acg and ./misc if you only want to use the representations. 3 SUPPORTING PLATFORMS It is possible to compile the package on any platform whenever a C++ compiler is available. A standard conforming C++ compiler is recommended (for example, GCC 3.4 and later, MSVC 7.1 and later). For legacy compilers, even they can compile, there could be problems. It seems MSVC 6.0 works but GCC 3.2 generates buggy executables. YMMV. 4 BUILD THE DEMO The demo reads GSRC benchmarks and performs area or area+HPWL optimizations using either of the two representations. Also this is a good chance to see if your compiler works. a. GNU Make and GCC - First 'make depends Config=release'. - Then 'make Config=release'. - Run './fplan_demoR ...'. - If the 'make' on your platform is not GNU Make, try 'gmake' instead. 5 ABOUT THE FLOORPLAN VIEWER The floorplan viewer works with Python 2.3 and wxPython 2.5.2.8 currently. Installing on Windows should be trouble-free once you get the binary installer from their websites. To use the viewer, first you need to use 'Open...' to load a floorplan (e.g. 'n100_acg.xml') with module positions and the representation information. Then you can load the interconnect (e.g. 'n100_aux.xml') via 'Load AUX file...'. 6 CONTACT US Prof. Hai Zhou, haizhou at eecs dot northwestern dot edu Jia Wang, jwa112 at eecs dot northwestern dot edu
