Quartus II - compile problem?

My cause is mentioned by Daixiwen (big loops generating some hardware at each iteration). I solve it by doing my function in each clock. For example, I want to do my function 1000 times. Instead of waiting for 1000 clocks and then using "for" loop to do my function (in one clock, 1000 functions are done), I do my function in each clock and count until 1000 clock to stop it (in one clock, 1 function is done, do it for 1000 clocks).
