SystemName [ABC: Logic synthesis and verification system.]
PackageName [extra]
Synopsis [Various reusable software utilities.]
Description [This library contains a number of operators and
traversal routines developed to extend the functionality of
CUDD v.2.3.x, by Fabio Somenzi (http://vlsi.colorado.edu/~fabio/)
To compile your code with the library, #include "extra.h"
in your source files and link your project to CUDD and this
library. Use the library at your own risk and with caution.
Note that debugging of some operators still continues.]
