The **alias** construct has largely been replaced by packed structures and the **let** construct. It is a way of providing a more user friendly name for another signal, or a select of another signal.

The alias construct provides one other feature that is to connect two different nets together without knowing the direction of data flow. That avoids extraneous buffers or assign statements.
