# convertbddcircuitabl(3)

converts a bdd node to an abl expression.

## NAME

convertbddcircuitabl - converts a **bdd** node to an **abl** expression.

## SYNOPSYS

```
#include "bdd101.h"
chain_list ∗convertbddcircuitabl( BddCircuit, BddNode )
  bddcircuit ∗BddCircuit;
  bddnode    ∗BddNode;
```

## PARAMETERS

- *BddCircuit*

  The **bdd** circuit.

- *BddNode*

  The **bdd** node to convert.

## DESCRIPTION

**convertbddcircuitabl** converts the **bdd** node to an **abl** expression. The *BddCircuit* is used to translate the variable nodes into atomic expressions. If a null pointer is given, the default **bdd** circuit is used.\

## RETURN VALUE

**convertbddcircuitabl** returns a pointer to the **abl** expression translated.

## 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_AND,
                            createablatom( "i0" ),
                            createablatom( "i1" ) );
   BddNode = addbddcircuitabl( BddCircuit, Expr );
   freeablexpr( Expr );
   Expr = convertbddcircuitabl( BddCircuit, BddNode );
   /* displays (i0 and i1) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
```
