NAME

       composeBdd - substitutes an index by a BDD in another BDD

SYNOPSYS

       #include "logmmm.h"
       pNode composeBdd(pBdd1,pBdd2,index)
       pNode pBdd1;
       pNode pBdd2;
       short index;

PARAMETERS

       pBdd1		   BDD in wich index is substituted

       pBdd2		   BDD that replaces index

       index		   index to substitute

DESCRIPTION

       composeBdd() constructs the graph for the function obtained by composing pBdd1 and pBdd2.  This function can  be  used  when  an  auxiliary
       variable has been mistaken for a primary input.

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 = composeBdd(res,notBdd(nodeB),2);  /* composition : a = (NOT B) */
       displayBdd(res,1);

       /* it will display
       @res   ONE
       */

       destroyBdd(1);

NAME

       decbddrefext - decrements the external reference of a bdd node.

ORIGIN

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 );
