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

       convertbddindexabl - converts a bdd index to an abl expression.

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"
       chain_list *convertbddnodeabl( BddSystem, NameArray, IndexArray, BddNode )
	 bddsystem *BddSystem;
	 char	  **NameArray;
	 bddindex  *IndexArray;
	 bddindex      Index;

PARAMETERS

       BddSystem	   The bdd system.

       NameArray	   The array of names.

       IndexArray	   The array of indexes.

       Index		   The bdd index to convert.

DESCRIPTION

       convertbddindexabl converts the bdd index Index to an abl expression in the bdd system BddSystem.  If a null pointer is given, the  default
       bdd  system is used.  The NameArray, and IndexArray parameters are used to translate the variable nodes into atomic expressions.  The array
       NameArray is list of names.  The array IndexArray does the correspondence between a bdd index and a slot in the NameArray. If the  IndexAr-
       ray parameter is a null pointer, then the name of the bdd index BDD_INDEX_MIN is assumed to be the first slot of the NameArray, and so on.

RETURN VALUE

       convertbddindexabl returns a pointer to the abl expression translated.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddnode    *BddNode;
	  chain_list *Expr;
	  char	     *NameArray[ 1 ];
	  BddSystem = createbddsystem( 100, 1000, 100, 50000 );
	  BddNode   = addbddvarlast( BddSystem );
	  NameArray[ 0 ] = namealloc( "i0" );
	  Expr = convertbddindexabl( BddSystem, NameArray, (bddindex *)0,  BddNode->INDEX );
	  /* displays i0 */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
