==============================================
Generating feedthrough from multiple instances
==============================================

This example demonstrates how to generate feedthrough from multiple instances.
If multiple instances belong to the same reference module it should reuser
the feedthrough instead of creating independent feedthrough to pass through each instance.

This example creates new wire ``A`` and create feedthrough port and connection
from  ``inst_1_0`` and  ``inst_1_1`` in sequence.
