SYNOPSYS






#include "bdd101.h"
void delbddnode( BddSystem, BddNode )
  bddsystem *BddSystem;
  bddnode   *BddNode;


PARAMETERS

BddSystem The bdd system.
BddNode The bdd node.

DESCRIPTION

delbddnode tries to delete the bdd node BddNode and its children, if they have not external reference, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The use of this function is not recommended because, it takes time. It is better to call the decbddrefext function, and do a garbage collection with the garbagebddsystem function.

RETURN VALUE

delbddnode returns nothing.

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 );
   delbddnode( (bddsystem *)0, decbddrefext( BddNode ) );
   /* displays (not i0) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem *)0 );
   destroybddcircuit( (bddcircuit *)0 );
