How to rewrite the following code using a for loop in Verilog?

Question

Is it possible to write the following code using a for loop in Verilog?

i = 0: sum[0] <= data[0];
i = 1: sum[1] <= data[0] + data[1];
i = 2: sum[2] <= data[0] + data[1] + data[2];
i = 3: sum[3] <= data[0] + data[1] + data[2] + data[3];
.
.
i = 7: sum[7] <= data[0] + data[1] + data[2] + data[3] + data[4] + data[5] + data[6] + data[7];

Answer 1

You can use a couple of for loops and a function:

logic [3:0] sum [8];
logic [7:0] data;
function logic [3:0] sum_data (int n);
 sum_data = data[0];
 for (int j=1; j<=n; j++) begin
 sum_data += data[j];
 end
endfunction
// ...
for (int i=0; i<8; i++) begin
 sum[i] <= sum_data(i);
end

Functions are synthesizable.
