Python tree_reduce Examples

Example #1

    def test_xor(self):
        wires, vals = utils.make_inputs_and_values(7, exact_bitwidth=8, dist=utils.uniform_dist)
        outwire = pyrtl.Output(name="test")

        import operator
        from six.moves import reduce
        outwire <<= pyrtl.tree_reduce(operator.xor, wires)

        out_vals = utils.sim_and_ret_out(outwire, wires, vals)
        true_result = [reduce(operator.xor, v) for v in zip(*vals)]
        self.assertEqual(out_vals, true_result)

Example #2

 def test_empty(self):
     with self.assertRaises(pyrtl.PyrtlError):
         import operator
         pyrtl.tree_reduce(operator.add, [])
