## Tactic pb2bv

### Short Description

Convert pseudo-boolean constraints to bit-vectors

### Example

```z3
(declare-const x Int)
(declare-const y Int)
(declare-const z Int)
(declare-const u Int)
(assert (<= 0 x))
(assert (<= 0 y))
(assert (<= 0 z))
(assert (<= 0 u))
(assert (<= x 1))
(assert (<= y 1))
(assert (<= z 1))
(assert (<= u 1))
(assert (>= (+ (* 3 x) (* 2 y) (* 2 z) (* 2 u)) 4))
(apply pb2bv)
```
