Hi,
I am trying to implement a particular code in verilog whose pseudo code is given below. I have problem with the while loop(LINE 7 & 11). I get this error when the while loop is used; Non-constant loop condition not supported for while. Can anybody suggest me an alternative.
Compute: X mod Y
1: G = Split(X;Width(Y ) )//split x in widths of y
2: N = Num(G) - 1// no. of groups that x is split into
3: while N > 0 do
4: T = G[N]
5: for i = Width(Y ) - 1 downto 0 do
6: T = T Y do
16: G[0] = G[0] - Y
return G[0]
while loops are only supported if they can be unrolled, i.e., the value is pre-determined and constant. However, note that using while loops for describing hardware is typically not a good idea. You should be using FSMs and other control structures, for which all you have to do is check some termination condition, and set the state back to the initial state if condition not met. It achieves the 'loop functionality' but in time.
