yes, the data was due to previous run. initial run (1st time), the initial result is 0,0,200, 0,2,4,6.... second run, the result was as in above. is it due to the block is running under same clock? 1st positive edge of the clk, 2nd read the data, 3rd data go into adder, 4th data go into fifo_out, 5th, data go out to be displayed as result.
