NAME

       constraintBdd - restricts a BDD to another BDD

SYNOPSYS

       #include "logmmm.h"
       pNode constraintBdd(pBdd1,pBdd2)
       pNode pBdd1;
       pNode pBdd2;

PARAMETERS

       pBdd1		   BDD to restrict

       pBdd2		   constraint BDD

DESCRIPTION

       constraintBdd() constructs the graph for the function obtained by restricting pBdd1 on pBdd2.  This function can be used for example when a
       primary input is stuck at 0 or 1.

EXAMPLE

       #include "mutnnn.h"	/* mbk utilities */
       #include "logmmm.h"
       pNode nodeA,nodeB;
       pNode res;

       initializeBdd(SMALL_BDD);
       nodeA = createNodeTermBdd(3);
       nodeB = createNodeTermBdd(3);
       res = applyBinBdd(OR,nodeA,nodeB); /* res = (OR a b)
       res = constraintBdd(res,nodeA);	       /* a = 1 */
       displayBdd(res,1);

       /* it will display
       @res   ONE
       */

       destroyBdd(1);

NAME

       applybddnodenot - complements a bdd.

SYNOPSYS

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

PARAMETERS

       BddSystem	   The bdd system.

       BddNode		   The bdd node to complement.

DESCRIPTION

       applybddnodenot complements BddNode in the bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

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

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 );
	  addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
	  addbddcircuitin( (bddcircuit *)0, "i1", 0, BDD_IN_MODE_FIRST );
	  BddNode = applybddnode( (bddsystem *)0,
				  ABL_AND,
				  searchbddcircuitin( (bddcircuit *)0, "i0" ),
				  searchbddcircuitin( (bddcircuit *)0, "i1" ) );
	  BddNode = applybddnodenot( (bddsystem *)0, decbddrefext( BddNode ) );
	  Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode );
	  /* displays (i0 nand i1) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
