SYNOPSYS

 #include "bdd101.h"
 bddassoc *addbddassoc( BddSystem )
   bddsystem  *BddSystem;
 

PARAMETERS

BddSystem
The bdd system.

DESCRIPTION

addbddassoc creates a new association variables in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

RETURN VALUE

addbddassoc returns a pointer to the new variable association.

ERRORS

"no more variable association, error !"
There is no variable association number left.

EXAMPLE

 #include "bdd101.h"

    bddcircuit *BddCircuit;
    bddnode    *BddNode;

    bddnode    *BddVariable;
    bddassoc   *Assoc;
    chain_list *Expr;
    bddvar         Variable;
    BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
    BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
