NAME

satisfybddnode - finds a satisfying path for a bdd node.

See the file buster/alliance/alc_origin.1.en.gz.

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 );
