what is the functionality of "or_reduce" function in VHDL ?

A:
crazyscot is quite right. Here's a precis:
It takes a std_logic_vector
and returns the result of using the VHDL OR
operator to or all the bits together. So if there's a X
, Z
, U
etc in the vector, you'll get the "strongest" of these back.
