man satisfybddnode (3): finds a satisfying path for a bdd node.

SYNOPSYS

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

PARAMETERS

BddSystem: The
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 );
