# Usage

This tutorial assumes familiarity with [py-aiger](https://github.com/mvcisback/py-aiger) and [py-aiger-bv](https://github.com/mvcisback/py-aiger-bv).

```python
import aiger_bv as BV
from aiger_bdd import to_bdd, from_bdd, count

x = BV.atom(3, 'x', signed=False) 

expr = x < 5  # Could be an AIG or AIGBV or BoolExpr.
bdd, manager, input2var = to_bdd(expr)  # Convert circuit encoded by expr into a BDD.
expr2 = from_bdd(bdd)  # Creates an Aiger Expression from a BDD.

assert count(expr, fraction=True) == 5/8
assert count(expr, fraction=False) == 5
```
