NAME

       cofactorbddnode - computes the generalized cofactor.

       Paris, France.

SYNOPSYS

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

PARAMETERS

       BddSystem	   The bdd system.

       BddNode1 	   The first bdd node.

       BddNode2 	   The second bdd node.

DESCRIPTION

       cofactorbddnode computes the generalized cofactor of BddNode1 by BddNode2, in the bdd system BddSystem.	If a null pointer  is  given,  the
       default bdd system is used.

RETURN VALUE

       cofactorbddnode returns the resulting bdd node.

ERRORS

       "index xxx out of range"
	      The BddNode2 parameter must be different to the zero bdd node.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddNode1;
	  bddnode    *BddNode2;
	  bddnode    *BddNode;
	  chain_list *Expr;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  Expr = createablbinexpr( ABL_OR,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode1 = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  Expr = createablbinexpr( ABL_AND,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode2 = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  BddNode = cofactorbddnode( (bddsystem *)0, BddNode1, BddNode2 );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays '1' */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );

RELPRODBDDNODEASSOC(3)						   BDD FUNCTIONS					    RELPRODBDDNODEASSOC(3)

NAME

       relprodbddnodeassoc - computes a relational product.

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/

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.
