How to Get CUDD

The CUDD Package

The CUDD package is available via anonymous FTP from vlsi.Colorado.EDU. A compressed tar file named cudd-2.4.1.tar.gz can be found in directory pub. Once you have this file,

gzip -dc cudd-2.4.1.tar.gz | tar xvf -

will create directory cudd-2.4.1 and its subdirectories. These directories contain the decision diagram package, a few support libraries, and a toy application based on the decision diagram package. There is a README file with instructions on configuration and installation in cudd-2.4.1. You can use a compiler for either ANSI C or C++.

Once you have made the libraries and program, you can type:

cd nanotrav
nanotrav -p 1 -autodyn -reordering sifting -trav mult32a.blif

This will run a simple-minded FSM traversal program. (On a 200 MHz PentiumPro (TM), it takes about 6 sec.) The output produced by the program can be checked against the contents of cudd-2.4.1/nanotrav/mult32a.out. More information on the nanotrav program can be found in cudd-2.4.1/nanotrav/README.

If you want to be notified of new releases of the CUDD package, send a message to Fabio@Colorado.EDU.

CUDD Friends

Two CUDD extensions are available via anonymous FTP from vlsi.Colorado.EDU.

• PerlDD is an object-oriented Perl5 interface to CUDD. It is organized as a standard Perl extension module. The Perl interface is at a somewhat higher level than the C++ interface, but it is not as complete.
• DDcal is a graphic BDD calculator based on CUDD, Perl-Tk, and dot. (See Section 3.18 for information on dot.)
