2.1.7 Net Labels
Using the same signal in many places in a design.
A netlabel component dispenses a signal to be used in several places in a logic design, which can increase the readability of a schematic by reducing the number of crossing lines.
For example, then inverted CLBIN1PPS signal is used immediately (connection not shown) and routed to a netlabel SWITCH.
The SWITCH signal can then be used elsewhere in the design as a source.
