code problem

Hi, I am wring a mermory code, but the waveform is not correct. There is no change of fin_add, only when add_en='1' then add_en_next change. I think probable it is coz the used(num) never become zero...

Apart from the question, if the presented code as a whole has a reasonable operation (I said, why it can't in my opinion), the usage of fin_add and fin_init in the process is reasonable as such. But when the for loop iteration is translated to combinational code, these signals loose their original function. As uilka_b pointed out, they never change, respectively they are eliminated.
