pass an undefined number of datasets

[Andreas]

Hello,
is there an easy way to pass an undefined number of datasets to an entity?
My solution is

entity
port(count: in integer;
data : real_vector(0 to 100)
);
end entity;

if one dataset is a real number (could be anything else). 'data' is a
vector(array), which contains all datasets. its length is 100 if I want
to pass 100 sets at most. 'count' is the number of datasets really used
in the current simulation cycle.

Is there perhabs a more effectiv, better way to pass an undefined number
of datasets?

Thanks,

Andreas

Hi,

Soory, I've forgotten to say, that the required number has be dynamic

during simulation and cann't be tetermined at compile time.

determined before it is implemented. You can have the largest possible
number and then use only a subset of them based on requirement.

Then you ought to be using functions
and procedures instead of entities.
