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 Université Pierre et Marie CURIE, in Paris,
       France.

SYNOPSYS
       #include "bdd101.h"
       chain_list *convertbddmuxabl( BddSystem, NameArray, IndexArray, Equation, BddHigh, BddLow )
         bddsystem  ΒddSystem;
         char      (*NameArray;
         bddindex   ΙndexArray;
         chain_list Εquation;
         bddnode    ΒddHigh;
         bddnode    ΒddLow;

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 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 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 );
