ADDBDDNODEASSOC(3)						   BDD FUNCTIONS						ADDBDDNODEASSOC(3)

NAME

       addbddnodeassoc - adds 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.

SYNOPSYS

       #include "bdd101.h"
       bddassoc *addbddnodeassoc( BddSystem, BddAssoc, Variable, BddNode )
	 bddsystem  *BddSystem;
	 bddassoc   *BddAssoc;
	 bddvar      Variable;
	 bddnode    *BddNode;

PARAMETERS

       BddSystem	   The bdd system.

       BddAssoc 	   The variable association.

       Variable 	   The variable number.

       BddNode		   The bdd node to add.

DESCRIPTION

       addbddnodeassoc adds the bdd node BddNode, 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 BddNode is incremented.

RETURN VALUE

       addbddnodeassoc returns a pointer to the variable association.

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    *BddNode;
	  bddnode    *BddSubst;
	  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" ) );
	  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 );
	  Assoc = addbddassoc( (bddsystem *)0 );
	  addbddnodeassoc( (bddsystem *)0, Assoc, Variable, BddSubst );
	  BddNode = substbddnodeassoc( (bddsystem *)0, BddSubst, Assoc );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays ((i3 or i2) and i1) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddassoc( (bddsystem *)0 );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );

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.
