Arrays-VHDL

1.In arrays(of real type ) how are we supposed to find the maximum value index in the array?I think A'HIGH is something different which gives the highest subscript of the array.What's the difference ...

1. It depends how you declare the array:

signal a: some_array_t(0 to 7);

signal b : some_array_t(7 downto 0);

a'high = 7;

a'right = 7;

b'high = 7;

b'high = 0;

does this makes sense?

2. you'll have to write a function to do it

NB - Real type is not synthesisable - so I assume this is all for testbenching.
