NAME

       simpbddnodedcon - simplifies a bdd with don't cares on its on-set part.

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 *simpbddnodedcon( BddSystem, BddOn, BddDc )
	 bddsystem *BddSystem;
	 bddnode   *BddOn;
	 bddnode   *BddDc;

PARAMETERS

       BddSystem	   The bdd system.

       BddOn		   The first bdd node.

       BddDc		   The second bdd node.

DESCRIPTION

       simpbddnodedcon simplifies the bdd node BddOn with BddDc, in the bdd system BddSystem.  If a null pointer is given, the default bdd  system
       is used.  The bdd node BddDc must be included imperatively in the on-set part of the bdd node BddOn.

RETURN VALUE

       simpbddnodedcon returns the simplified bdd node.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddOn;
	  bddnode    *BddDc;
	  bddnode    *BddNode;
	  chain_list *Expr;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  Expr = createablbinexpr( ABL_OR,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddOn = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  Expr = createablbinexpr( ABL_NOR,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddDc = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  BddNode = simpbddnodedcon( (bddsystem *)0, BddOn, BddDc );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays '1' */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
