    Hi,

    project source files are incomplete, e.g. many missing modules, e.g. max21_param, counter, comparator_equal, buffer, thus can't check the design.

    Notice that you don't have a testbench for top level design, without simulating the full design succesfully you can't claim that it simulates o.k.

    A possible source of hardware-to-simulation mismatch is the use of ripple clocks clk_0_5s and clk 1s that may cause timing failure. Better use one system clock (50 MHz clock) together with low frequency clock enable pulses.
