In reply to veli:

You cannot put a generate-for loop inside an always block. But you can put procedural-for loop inside an always block, or put an always block inside a generate-for loop. I think you wanted

always_comb begin
    // Default assignment:
    res = '0;
 
    for (int i = 0; i < DEPTH; i++) begin
        for (int y = 0; y < WIDTH; y++) begin
            res[i] = res[i] || arr[i][y]; // note arr index [i][y]
        end
    end
end
