Initial process does not run?

Hi everyone, I have an Initial process which assigns values to some variables, but I cannot get these variables' value in a clocked process. Anyone can help me?

"initial" is only used in test benches, it can not be used for code running in an FPGA.

Although I'm not much of a verilog guy, I think the for loop is constructed incorrectly. Try 

bit Array;
initial begin
  byte i;
  for (i=20; i>=0; i--) begin
    Array = 1;
  end
end
always @ (posedge PLL)
  begin
    // Array value returns 0 at all elements here
  end
