CONVERTBDDMUXABL(3)						   BDD FUNCTIONS					       CONVERTBDDMUXABL(3)

NAME

       convertbddmuxabl - converts two bdd nodes to an abl multiplexor 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 *convertbddmuxabl( BddSystem, NameArray, IndexArray, Equation, BddHigh, BddLow )
	 bddsystem  BddSystem;
	 char	   (*NameArray;
	 bddindex   IndexArray;
	 chain_list Equation;
	 bddnode    BddHigh;
	 bddnode    BddLow;

PARAMETERS

       BddSystem	   The bdd system.

       NameArray	   The array of names.

       IndexArray	   The array of indexes.

       Equation 	   The multiplexor command.

       BddHigh		   The first bdd node.

       BddLow		   The second bdd node.

DESCRIPTION

       convertbddmuxabl creates the following abl expression ( BddHigh AND Equation ) OR ( BddLow AND (NOT Equation ) ) in the bdd system  BddSys-
       tem.  If a null pointer is given, the default bdd system is used.  The NameArray, and IndexArray parameters are used to translate the vari-
       able nodes into atomic expressions.  The array NameArray is list of names.  The array IndexArray does the correspondence between a bdd node
       index  and  a slot in the NameArray. If the IndexArray 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

       convertbddmuxabl returns a pointer to the abl expression translated.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddnode    *BddNode1;
	  bddnode    *BddNode2;
	  chain_list *Expr;
	  char	     *NameArray[ 2 ];
	  BddSystem = createbddsystem( 100, 1000, 100, 50000 );
	  BddNode1  = addbddvarlast( BddSystem );
	  BddNode2  = addbddvarlast( BddSystem );
	  NameArray[ 0 ] = namealloc( "i0" );
	  NameArray[ 1 ] = namealloc( "i1" );
	  Expr = convertbddmuxabl( BddSystem, NameArray, (bddindex *)0,
				   createablatom( "C" ),  BddNode1, BddNode2 );
	  /* displays (i0 and C) or (i1 and (not C)) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
