You could always use the or_reduce function in std_logic_misc if you have
the appropriate data types, or write your own which would be similar to the
other reply already posted:
---------------
function or_reduce ( vec : std_logic_vector ) return std_logic is
variable result : std_logic := '0';
begin
for i in vec'range loop
result := result or vec(i);
end loop;
end function or_reduce;
---------------
global_b <= or_reduce(b);
---------------
That's what I do, because I'm usually not working with std_logic_vector data
types.
