Graphic Editor: Tri-State Buses Connected to a Bidirectional Bus
This example implements an 8-bit bus that feeds and receives
feedback from bidirectional pins. The example contains 8 D-type flipflops (DFFs)
named a, which store the
values of the inputs. The DFFs named b store the data
from the feedback line.
This example uses a WIRE primitive to clarify the bus
names. The WIRE primitive is used only for node naming and does not have a physical implementation
in the device architecture.
