3 This directory contains a set of packages that allow you to build a toy
4 application based on the CUDD package.
6 The CUDD package is a package written in C for the manipulation of
7 decision diagrams. It supports binary decision diagrams (BDDs),
8 algebraic decision diagrams (ADDs), and Zero-Suppressed BDDs (ZDDs).
10 The toy application provided in this kit is called nanotrav and is a
11 simple-minded FSM traversal program. (See the README file and the man
12 page nanotrav.1 in the nanotrav directory for the details.) It is
13 included so that you can run a sanity check on your installation.
17 Before you build the libraries and programs, you need to check the
18 Makefile in the top directory. Go through the definitions contained in the
19 configuration section, and select the desired compiler and compilation
20 flags. Instructions are provided in the comments of the Makefile.
22 You can always specify the options on the command line. For instance,
23 on some machines you can build a "fast" version of the program by typing:
25 make DDDEBUG= MTRDEBUG= ICFLAGS=-O2
27 The Makefile supports several targets:
30 Creates a "plain" version of the program.
33 Builds a test program (testdddmp) for BDD loading from and
34 storing to disk. See file README.test in the dddmp directory for
35 how to run the program.
38 Builds a test program for the C++ interface. Requires a C++
39 compiler. To run the program, run obj/testobj.
42 Builds a test program for CUDD. To run the program, go to the
43 cudd directory and type "./testcudd -p 2 r7x8.1.mat". The result
44 can be compared to r7x7.1.out.
47 Builds a test program for the mtr package. To run the program,
48 go to the mtr directory and type "./testmtr -p 1 test.groups".
51 Cleans directories, but leaves libraries and programs.
54 Cleans thoroughly, returning the directories to their pristine
57 The following targets are more or less obsolete and may disappear or
61 Creates a version of the program with the mnemosyne library
62 linked to it. It also builds the mnemalyse program, which
63 helps in finding memory leaks. This target does not work on the
64 IBM RS6000. The makefile also supports purify. To use purify,
65 set the PURE variable in the Makefile, and use the standard
69 Builds a version of the program using the u-code compiler
70 available on DEC machines (DECstations and Alphas). The newer
71 native compiler on the Alphas does not use u-code, though.
72 Therefore the standard target should be used with it.
75 Runs lint on all subdirectories except mnemosyne. Creates lint
76 libraries for all object libraries.
79 Builds ctags-style tag files for all subdirectories except
83 Makes all of the above, except check_leaks, which is
84 incompatible with a plain "make."
86 All targets, except clean and distclean, will create the include
87 directory if it does not already exist.
89 The Makefile does not compile the SIS interface (cuddBddPort.c and
90 cuddPwPt.c found in subdirectory sis). To compile the interface, you
91 also need array.h and var_set.h, which are not part of this
92 distribution, but come with SIS. Detailed instructions on how to
93 integrate the CUDD package in SIS can be found in the documentation

136 (**) Some old versions of the AIX cc compiler have buggy optimizers:
137 Try compiling with -O2 instead of -O3 if the program crashes.
139 Running lint and compiling with gcc -Wall still produces warnings.
140 Running `purify' under Solaris 2.8 generates no messages.
144 This kit has also been built on a PC running Windows98, Windows NT,
145 and Windows XP using the Cygnus port of the GNU tools
146 (http://www.cygwin.com/.) This release of CUDD was tested under Windows
147 XP with versions 1.5.5-1 of the Cygwin DLL. Both gcc and g++ were used.
148 The time measurement functions do not work under Windows98. You must have
149 bash set up properly for make to work. See also the instructions in Makefile.
153 The directory `nanotrav' contains a very simple application based on the
154 CUDD package. The `nanotrav' directory contains a man page that
155 describes the options nanotrav supports. The files *.blif are sample
156 input files for nanotrav.
158 If you have built the mnemosyne library (make check_leaks), you can do
161 This does not work on machines running SunOS, but the version of
162 nanotrav that uses mnemosyne may work.
166 Directory cudd-2.4.1/cudd/doc contains HTML documentation for the CUDD
167 package. The recommended starting point is cuddIntro.html. Documentation
168 in both postscript(tm) format and plain text format is also provided.
169 Documentation for the auxiliary libraries (except for the util library)
170 is in the doc subdirectories.
