NAME

       satisfybddnode - finds a satisfying path for a bdd node.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗satisfybddnode( BddSystem, BddNode )
         bddsystem ∗BddSystem;
         bddnode   ∗BddNode;

PARAMETERS

       BddSystem           The bdd system.

       BddNode             The bdd node.

DESCRIPTION

       satisfybddnode  finds  a simple path throw the bdd BddNode that reaches the constant bdd node one, in the
       bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       satisfybddnode returns a bdd node that satisfies BddNode.

ERRORS

       "index xxx out of range, error !"
              The BddNode parameter must be different from the bdd node zero.

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 );
          Expr = createablbinexpr( ABL_OR,
                                   createablatom( "i0" ),
                                   createablatom( "i1" ) );
          BddNode = addbddcircuitabl( BddCircuit, Expr );
          freeablexpr( Expr );
          BddNode = satisfybddnode( (bddsystem ∗)0, BddNode );
          Expr = convertbddcircuitabl( BddCircuit, BddNode );
          /* displays  i0 */
          viewablexpr( Expr, ABL_VIEW_VHDL );
          freeablexpr( Expr );
          destroybddsystem( (bddsystem ∗)0 );
          destroybddcircuit( (bddcircuit ∗)0 );
