carry tests

This directory contains test for the v2x_to_model.py and v2x_to_pb_type tools. The tests use model defined in CBLOCK tests. Those tests should check the following features:

Blackbox detection

• [ ] model of the leaf pb_type is generated
• [ ] leaf pb_type xml is generated
• [ ] all dependency models and pb_types are included in the output files

Carry chain inference

• [ ] automatic inference of carry chains - carry chains defined on ports of included blocks should be propagated to top level module
