DECBDDREFEXT(3) 						   BDD FUNCTIONS						   DECBDDREFEXT(3)

NAME

       decbddrefext - decrements the external reference of a bdd node.

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 *decbddrefext( BddNode )
	 bddnode *BddNode;

PARAMETERS

       BddNode		   The bdd node.

DESCRIPTION

       decbddrefext decrements the number of external reference of the bdd node BddNode.

RETURN VALUE

       decbddrefext returns the BddNode pointer.

ERRORS

       "negative reference, index xxx error !"
	      The BddNode must have a postive number of external reference.

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 );
	  decbddrefext( BddNode );
	  /* displays Node VAR: 0  INDEX: 2  MARK: 0  REF_EXT: 0  REF_INT: 0 */
	  viewbddnode( (bddsystem *)0, BddNode );
	  /* displays (not i0) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
