ADDBDDNODE(3)							   BDD FUNCTIONS						     ADDBDDNODE(3)

NAME

       addbddnode - adds a new bdd node in the bdd system.

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 *addbddnode( BddSystem, Index, High, Low  )
	 bddsystem *BddSystem;
	 bddindex   Index;
	 bddnode   *High;
	 bddnode   *Low;

PARAMETERS

       BddSystem	   The bdd system.

       Index		   The bdd index.

       High		   The bdd high pointer.

       Low		   The bdd low pointer.

DESCRIPTION

       addbddnode adds a new node with the index Index, High as HIGH pointer, and Low as LOW pointer in the bdd system BddSystem. If the bdd  node
       exist already addbddnode return its pointer.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       addbddnode returns a pointer to the resulting bdd node with its number of external reference incremented.

ERRORS

       "index xxx out of range"
	      The Index parameter must be a valid index.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddNode;
	  chain_list *Expr;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  BddNode = addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
	  BddNode = addbddnode( (bddsystem *)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH );
	  Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode );
	  /* displays (not i0) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
