This is version 2 of NuSMV, the New Symbolic Model Verifier.
----------------------------------------------------------------------
NuSMV is a re-implementation and extension of SMV, the first model
checker based on BDDs. It has been designed to be an open architecture
for model checking, which can be reliably used for the verification of
industrial designs, as a core for custom verification tools, and as a
test-bed for formal verification techniques.
NuSMV version 2 extends NuSMV with new model checking algorithms and
techniques. It combines classical BDD-based symbolic techniques with
SAT-based techniques. It also presents other new features: for
instance, it allows for a more powerful manipulation of multiple
models; it can generate flat models for the whole language; it allows
for cone of influence reduction.
The BDD-based model checking component exploits the CUDD library
developed by Fabio Somenzi at Colorado University. The SAT-based
model checking component includes an RBC-based Bounded Model
Checker, connected to a SAT solver to be compiled separately
(instructions and building support are batteries included in
NuSMV, details are underneath).
The currently available SAT solvers are:
+ The MiniSat SAT library developed by Niklas Een or Niklas Sorensson.
+ The ZCHAFF SAT library developed by the Princeton University
NuSMV version 2 is distributed with an OpenSource license, namely the
GNU Lesser General Public License version 2 (LGPL-2). The aim is to
provide a publicly available state-of-the-art symbolic model
checker. With the OpenSource development model, a whole community
participates in the development of a software systems, with a
distributed team and independent peer review. This may result in a
rapid system evolution, and in increased software quality and
reliability: for instance, the OpenSource model has boosted the
take-up of notable software systems, such as Linux and Apache. With
the NuSMV OpenSource project, we would like to reach the same goals
within the model checking community, opening the development of NuSMV.

3. BUILDING NUSMV FROM SOURCE CODE
==================================
To compile NuSMV 2 follow the instructions below.
NOTE: NuSMV is also distributed already compiled for the most common
operating systems and architectures. See the "BINARY DISTRIBUTION"
section for instructions on how to install an already compiled
package.
NOTE: platform specific instructions for building NuSMV are contained
in the "PLATFORMS" section.
3.1 Requirements
----------------
To build NuSMV, CUDD, MiniSat and/or ZChaff as them are distributed,
you will need:
* An ANSI C compiler (gcc will do, as will several versions of cc)
* An ANSI C++ compiler (g++ will do)
* GNU Flex version 2.5 or greater
* GNU Bison version 1.22 or greater
* cmake utility version 2.8 or greater
* GNU make utility version 3.74 or greater
* GNU patch utility
* GNU tar and gzip utilities
* Library libxml2
* Approximately 45 MB of free disk space for building the system
(76MB with optional documentation)
* Approximately 30 MB of free disk space for the installation
A few tools and libraries are required to have full features provided,
but they are not strictly required to build NuSMV.
In particular:
* A fully working 'latex' environment for generation of documentation
* Program 'doxygen' for generation of the programmer's documentation
* Library 'readline' for a shell usability improvement.
3.2 Building steps
------------------
1. Download the most recent versions of NuSMV's source code from the
address above into a convenient directory, e.g., /tmp.
2. Move to the directory where you would like to build NuSMV and unpack the
distributions:
% cd /home/nusmv # for example
% gzip -dc /tmp/NuSMV-2.6.0.tar.gz | tar xf -
This will unpack in a new directory "<TOPDIR>"
3. MiniSat and (on request) ZCHAFF solvers are downloaded and compiled
automatically when compiling NuSMV. However if download is not
possible during compilation, it is possible to download them
separately before compiling NuSMV. See For instructions on how to
download, compile and link MiniSat and ZChaff with NuSMV, read
files README.MiniSat' and 'README.zChaff', respectively.
IMPORTANT: at least one SAT solver must be provided.
4. Move into the [...]/<TOPDIR>/NuSMV directory and:
4.1 Create a directory for building, and enter into it
% pwd
[...]/<TOPDIR>/NuSMV
% mkdir build
% cd
% pwd
[...]/<TOPDIR>/NuSMV/build
4.2 Configure by invoking cmake
% cmake ..
-- The C compiler identification is GNU 4.4.7
-- The CXX compiler identification is GNU 4.4.7
[...]
-- Build files have been written to: [...]/<TOPDIR>/NuSMV/build
OPTIONAL: MiniSat is enabled by default, whilst for licensing
issues zChaff is disabled by default. If you want to use a
different setting, set ENABLE_MINISAT and/or ENABLE_ZCHAFF cmake
variables. Setting cmake variables can be done by editing
configuration file [...]/<TOPDIR>/NuSMV/build.CMakeCache.txt or
directly when invoking cmake. For example:
% cmake .. -DENABLE_ZCHAFF=ON
Note: Not all checks done when configuring will return
successfully. This is normal and should not affect compilation if
configuration ends without errors.
Note: cmake offers a set of variables which can be used to change
wrong guess or defaults you may not want. See
[...]/<TOPDIR>/NuSMV/build.CMakeCache.txt for the list of variables
and their values.
Note: For further information see the "INSTALLING NUSMV" section
below.
Note: by default infinite-width words are disabled, i.e. the
maximum width of words is limited to 64. To enable infinite width,
set variable ENABLE_BIGNUMBERS when calling cmake:
% cmake .. -DENABLE_BIGNUMBERS=ON
Use of infinite-width words libgmp is required to be installed.
Note: there are several cmake variables allowing for tailoring. See
NuSMV/CMakeList.txt file for further information. Variables can be
set either when invoking cmake, or by editing CMakeCache.txt file
which is created by calling cmake the first time. Refer to the
instructions provided with cmake for further information about how
variables can be set.
4.3 If configuration was successful, compile NuSMV
% pwd
[...]/<TOPDIR>/NuSMV/build
% make
This is expected to build an executable "NuSMV" in the
[...]/<TOPDIR>/NuSMV/build/bin directory.
NuSMV tries finding file "master.nusmvrc" in the directory given by
the environment variable NUSMV_LIBRARY_PATH. Set this to the
"share" directory in the source tree. For example for bash shell:
% export NUSMV_LIBRARY_PATH=[...]/<TOPDIR>/NuSMV/share/nusmv
5. OPTIONAL: Verify that NuSMV works by running it on some of the
examples included in the distribution:
% make check
============
4. PLATFORMS
============
NuSMV has been tested in a range of architecture/operating system
combinations. It has been tested on PC Intel, Apple Mac and Sun
architectures, with different versions and distributions of Linux,
Solaris, Windows and Mac OS X.
NuSMV-2.4.2 and later versions can be compiled natively at 64 bits.
File README_PLATFORMS.txt provides detailed information about each
supported platform.
===================
5. INSTALLING NUSMV
===================
Administrators and people who want to discard the source after building
NuSMV will want to install NuSMV in a central area:
* To install the NuSMV executable, library, headers, and help files, type,
while in the nusmv directory,
% make install
By default, this will put binaries, libraries, headers, and help files
in /usr/local/bin, /usr/local/lib, /usr/local/include, and /usr/local/share
respectively. To choose a different location, provide a default prefix
when you invoke configure, e.g., to install in /opt/NuSMV/bin, etc.,
set variable CMAKE_INSTALL_PREFIX. E.g.:
% pwd
[...]/<TOPDIR>/NuSMV/build
% cmake .. -DCMAKE_INSTALL_PREFIX=/opt/nusmv
when configuring NuSMV.
"make clean" removes all the files generated during "make". This is
useful when you want to rebuild NuSMV with a different prefix, when you
want to rebuild with different compiler options, etc.
The path "${CMAKE_INSTALL_PREFIX}/share/nusmv" is hard-coded into NUSMV.
In this directory, NuSMV expects to find "master.nusmvrc".
This may be overridden by setting the environment variable
"NUSMV_LIBRARY_PATH" to the name of an alternate directory, e.g. for
bash shell:
% export NUSMV_LIBRARY_PATH=/opt/nusmv/share/nusmv
======================
6. BINARY DISTRIBUTION
======================
NuSMV is also distributed already compiled. To install the binary
distribution of NuSMV follows the instructions below:
1. Download the most recent versions of NuSMV from the addresses
listed above into a convenient directory, (e.g., /tmp).
2. Move to the root directory where you want to install NuSMV. Let's
say "/opt" and untar the distribution:
% cd /opt
% gzip -dc /tmp/NuSMV-X.Y.Z-Linux-i686.tar.gz | tar xf -
This command will create a directory "/opt/nusmv-X.Y.Z"
containing the NuSMV files (X.Y.Z is the release number).
3. Optionally, add the directory /opt/nusmv-X.Y.Z/bin to your command
search PATH environment variable. E.g. for bash shell:
% export PATH=${PATH}:/opt/nusmv-X.Y.Z/bin
4. Optionally, set the NUSMV_LIBRARY_PATH environment
variable. E.g. for bash shell:
% export NUSMV_LIBRARY_PATH=/opt/nusmv-X.Y.Z/share/nusmv
5. Now you are ready to run and enjoy NuSMV.
% NuSMV -int # to run the interactive mode
