unconstrained array in case..is

[Xin Xiao]

What's the "technical" reason why it is not possible to write

case Signal is
....

....

with "Signal" being an unconstrained array?

Does this mean that you cannot write a generic entry if it is going to be
used in a "case..is" statement?

How can I cover all the cases
without knowing how many there are?

No. I could declare and use a subtype that matches the
width of a port or generic. For example:

subtype char_t is std_logic_vector(readData'range);
