# satisfybddnode(3)

finds a satisfying path for a bdd node.

## 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 );
```
