Quoting from the Basic HAL Tutorial section on net:

"The command net creates a connection between a signal and and one or 
more pins. If the signal does not exist net creates the new signal. This 
replaces the need to use the command newsig. The optional direction 
indicators <=, => and <=> are only to make it easier for humans to 
follow the logic and are not used by the net command."

and, farther down,

"A pin can be connected to a signal if it obeys the following rules:

An IN pin can always be connected to a signal

An IO pin can be connected unless there’s an OUT pin on the signal

An OUT pin can be connected only if there are no other OUT or IO pins on 
the signal"
