COMPOSEBDDNODE(3)						   BDD FUNCTIONS						 COMPOSEBDDNODE(3)

NAME

       composebddnode - substitutes a variable by a bdd in another bdd.

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.

SYNOPSYS

       #include "bdd101.h"
       bddnode *composebddnode( BddSystem, BddNode, Variable, BddSubst )
	 bddsystem *BddSystem;
	 bddnode   *BddNode;
	 bddvar     Variable;
	 bddnode   *BddSubst;

PARAMETERS

       BddSystem	   The bdd system.

       BddNode		   The bdd node.

       Variable 	   The variable to find.

       BddSubst 	   The bdd to substitute with.

DESCRIPTION

       composebddnode substitutes all the occurency of the variable Variable in the bdd node BddNode by the bdd node BddSubst, in the  bdd  system
       BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       composebddnode returns the resulting bdd node.

ERRORS

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

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddVariable;
	  bddnode    *BddNode;
	  bddnode    *BddSubst;
	  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" ) );
	  BddNode = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  Expr = createablbinexpr( ABL_OR,
				   createablatom( "i2" ),
				   createablatom( "i3" ) );
	  BddSubst = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" );
	  Variable = getbddvarbyindex( (bddsystem *)0, BddVariable->INDEX );
	  BddNode = composebddnode( (bddsystem *)0, BddNode, Variable, BddSubst );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays (i1 and (i2 or i3)) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );

NAME

       existbddnodeassocoff - computes an existantial quantification.

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 *existbddnodeassocoff( BddSystem, BddNode, BddAssoc )
	 bddsystem *BddSystem;
	 bddnode   *BddNode;
	 bddassoc  *BddAssoc;

PARAMETERS

       BddSystem	   The bdd system.

       BddNode		   The bdd node to treat.

       BddAssoc 	   The variable association.

DESCRIPTION

       existbddnodeassocoff suppress in the bdd node BddNode complemented, all the variables associated with something in the variable association
       BddAssoc, in the bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       existbddnodeassocoff returns the computed bdd node.

ERRORS

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

EXAMPLE

	  bddvar	 Variable;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
