What clock speed have you specified in your SDC file? without one, Timequest will check the timing at 1000Mhz (which is much faster than is realistically acheiveable). But it will report the fmax for the circuit (which is the fastest clock speed you could run the design at).

Thank you Trichky,

Using your informations i was able solve problems. Now i have a synchronous adder without errors. So, how to calculate the total execution time of this adder by using "TimeQuest Timing Analyser" ?

Best Regards,
