I just checked the allmighty VHDL book and it told me that
identifier in VHDL:
* may contain alpha numeric characters and underscores
* must start with a character
* must not end with a underscore
* must not have two consecutive underscores
so the suggested _n looks ok.
I personaly do not like the "negation bar" in source code
as i either use positive logic (there is no need for negative
logic within a synchronus design) or have few explicit signals
for which it is clear by their name that they are negative logic
(which are at the interfaces to the outside world only anways).
