RE: Ref. Doc. for "#" for active low

[Shepard Bob-G14751 <Bob.Shepard@motorola.com>]

It seems to be an Intel practice to use the "#" postfix to 
designate active low signals.  Intel developed the PCI and 
their practice stuck.  It's a good thing PCI wasn't developed 
by DEC so we don't use "_l".

What symbol is recommended in your "IEEE Standard for Logic 
Circuit Diagrams"?  Does it apply to text publications as 
well?

Both the PCI and the PCMCIA specs use "#" as the trailing 
character for the names of active low signals.  What standard 
or spec defines that usage?  Not ANSI/IEEE 991-1986.
