SYNOPSYS

       #include "bdd101.h"
       bddnode *relprodbddnodeassoc( BddSystem, BddNode1, BddNode2, BddAssoc )
	 bddsystem *BddSystem;
	 bddnode   *BddNode1;
	 bddnode   *BddNode2;
	 bddassoc  *BddAssoc;

PARAMETERS

       BddSystem	   The bdd system.

       BddNode1 	   The first bdd node.

       BddNode2 	   The second bdd node.

       BddAssoc 	   The variable association.

DESCRIPTION

       relprodbddnodeassoc computes BddNode1 AND BddNode2, and suppress the variables associated with something in the variable association BddAs-
       soc, in the bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       relprodbddnodeassoc returns the computed bdd node.

ERRORS

       "bad variable association xxx, error !"
	      The BddAssoc parameter must a valid variable association.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddNode;
	  bddnode    *BddNode1;
	  bddnode    *BddNode2;
	  bddnode    *BddVariable;
	  bddassoc   *Assoc;
	  chain_list *Expr;
	  bddvar	 Variable;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  Expr = createablbinexpr( ABL_AND,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode1 = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  Expr = createablbinexpr( ABL_OR,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode2 = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" );
	  Variable = getbddvarbyindex( (bddsystem *)0, BddVariable->INDEX );
	  Assoc = addbddassoc( (bddsystem *)0 );
	  addbddnodeassoc( (bddsystem *)0, Assoc, Variable, BddSystem->ONE );
	  BddNode = relprodbddnodeassoc( (bddsystem *)0, BddNode1, BddNode2, Assoc );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays i1 */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddassoc( (bddsystem *)0 );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );

DELBDDNODEASSOC(3)						   BDD FUNCTIONS						DELBDDNODEASSOC(3)

NAME

       delbddnodeassoc - deletes a bdd node in a variable association.

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

       Web : http://asim.lip6.fr/recherche/alliance/
       E-mail : alliance-users@asim.lip6.fr

SYNOPSYS

       #include "bdd101.h"
       int delbddnodeassoc( BddSystem, BddAssoc, Variable )
	 bddsystem  *BddSystem;
	 bddassoc   *BddAssoc;
	 bddvar      Variable;

PARAMETERS

       BddSystem	   The bdd system.

       BddAssoc 	   The variable association.

       Variable 	   The variable number.

DESCRIPTION

       delbddnodeassoc deletes the bdd node associated to the variable number Variable, in the variable association BddAssoc, in  the  bdd  system
       BddSystem.   If	a  null  pointer is given, the default bdd system is used.  The number of external reference of the associated bdd node is
       incremented.

RETURN VALUE

       delbddnodeassoc returns 1 if the variable is found, 0 otherwise.

ERRORS

       "variable xxx out of range, error !"
	      The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.
