Alternatively, I could declare an array that is 2^16 words deep and can be indexed using the random number. This would essentially synthesize a ROM block in Quartus. But in case I have multiple such arrays, I'm going to run out of internal memory very quickly. ...
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 between A'HIGH and A'RIGHT (low to high indexes).?
VHDL probably allows you to have two dimensional arrays in the component's ports.Verilog does not...

While the previous examples work for vectors as well as arrays of any kind, using the shift_left function only works with bit vectors. The definition of the shift_left function and it’s complementary shift_right function appears in the ieee.numeric_std package. It requires an unsigned vector...
