Hi *,
I know the whole numeric_std vs. std_logic_arith issue has been covered
several times before here, but please bear with me for a second
Does anyone of you have any concrete examples of problems that came up
because std_logic_arith was used? Code examples that behave differently
in different simulators/synthesis tools maybe? When I look at the
discussions about this issue in the past, it's always "std_logic_arith
should not be used, because it's not a standard and might be implemented
differently in different tools". But I've never seen actual examples or
heard of a problems arising from use of std_logic_arith.
I personally have always used numeric_std, because that's the way I
learned it. But when I talk about this with colleagues, the "use it
because it's a standard"-argument never beats the "I've been using
std_logic_arith forever, never had the slightest problems and don't see
why I should ever change anything"-argument.
So I'd be glad if maybe someone could share some "war stories" or
something.
cu,
Sean

Replace MONTH with the three-letter-abbreviation for the current
month. Simple, eh?
