How to cast a large std_logic_vector to an array of smaller ones?

Hi again, For my project, I've defined a custom data type which actually is an array of 16 8-bit std_logic_vectors: TYPE census_line IS ARRAY(0 TO 15) OF std_logic_vector(7 downto 0); ...

Problem solved :)

Using larger std_logic_vectors somehow reduced optimization freedome for quartus.

When I switched to M10K-blocks for instead of registers, resource-useage went down to 1.1k ALMs which is actually great :)

Thanks!
