DEPRECATED CUDD 3.0.0 has support for building shared object files. Download it from here: http://vlsi.colorado.edu/~fabio/. $Id$ This directory contains a set of packages that allow you to build a toy application based on the CUDD package. The CUDD package is a package written in C for the manipulation of decision diagrams. It supports binary decision diagrams (BDDs), algebraic decision diagrams (ADDs), and Zero-Suppressed BDDs (ZDDs). The toy application provided in this kit is called nanotrav and is a simple-minded FSM traversal program. (See the README file and the man page nanotrav.1 in the nanotrav directory for the details.) It is included so that you can run a sanity check on your installation. INSTALLATION Before you build the libraries and programs, you need to check the Makefile in the top directory. Go through the definitions contained in the configuration section, and select the desired compiler and compilation flags. Instructions are provided in the comments of the Makefile. You can always specify the options on the command line. For instance, on some machines you can build a "fast" version of the program by typing: make DDDEBUG= MTRDEBUG= ICFLAGS=-O2 The Makefile supports several targets: make: Creates a "plain" version of the program. make testdddmp: Builds a test program (testdddmp) for BDD loading from and storing to disk. See file README.test in the dddmp directory for how to run the program. make testobj: Builds a test program for the C++ interface. Requires a C++ compiler. To run the program, run obj/testobj. make testcudd: Builds a test program for CUDD. To run the program, go to the cudd directory and type "./testcudd -p 2 r7x8.1.mat". The result can be compared to r7x7.1.out. make testmtr: Builds a test program for the mtr package. To run the program, go to the mtr directory and type "./testmtr -p 1 test.groups". make clean: Cleans directories, but leaves libraries and programs. make distclean: Cleans thoroughly, returning the directories to their pristine state. The following targets are more or less obsolete and may disappear or change in the future. make check_leaks: Creates a version of the program with the mnemosyne library linked to it. It also builds the mnemalyse program, which helps in finding memory leaks. This target does not work on the IBM RS6000. The makefile also supports purify. To use purify, set the PURE variable in the Makefile, and use the standard target. make optimize_dec: Builds a version of the program using the u-code compiler available on DEC machines (DECstations and Alphas). The newer native compiler on the Alphas does not use u-code, though. Therefore the standard target should be used with it. make lint: Runs lint on all subdirectories except mnemosyne. Creates lint libraries for all object libraries. make tags: Builds ctags-style tag files for all subdirectories except mnemosyne. make all: Makes all of the above, except check_leaks, which is incompatible with a plain "make." All targets, except clean and distclean, will create the include directory if it does not already exist. The Makefile does not compile the SIS interface (cuddBddPort.c and cuddPwPt.c found in subdirectory sis). To compile the interface, you also need array.h and var_set.h, which are not part of this distribution, but come with SIS. Detailed instructions on how to integrate the CUDD package in SIS can be found in the documentation (cudd/doc). PLATFORMS This kit has been successfully built on the following configurations: PC (ia32 and ia64) running Ubuntu with gcc PC (ia32 and ia64) running Ubuntu with g++ PC (ia32 and ia64) running Linux RedHat with gcc PC (ia32 and ia64) running Linux RedHat with g++ PC (ia64) running Cygwin on Windows 7 and Vista with gcc PC (ia64) running Cygwin on Windows 7 and Vista with g++ Platforms to which I have no longer access and therefore are no longer supported.

(**) Some old versions of the AIX cc compiler have buggy optimizers: Try compiling with -O2 instead of -O3 if the program crashes. Running lint and compiling with gcc -Wall still produces warnings. Running `purify' under Solaris 2.8 generates no messages. SANITY CHECK The directory `nanotrav' contains a very simple application based on the CUDD package. The `nanotrav' directory contains a man page that describes the options nanotrav supports. The files *.blif are sample input files for nanotrav. If you have built the mnemosyne library (make check_leaks), you can do cd mnemosyne make runmtest This does not work on machines running SunOS, but the version of nanotrav that uses mnemosyne may work. DOCUMENTATION Directory cudd-2.5.0/cudd/doc contains HTML documentation for the CUDD package. The recommended starting point is cuddIntro.html. Documentation in both postscript(tm) format and plain text format is also provided. Documentation for the auxiliary libraries (except for the util library) is in the doc subdirectories.
