xfft ip core problem

Hello Sir.

    When I add FFT IP in my design,  then I use vivado run my top design simulation. The simulation crashed at elaboration phase, and the information is the fllow:

---------------------------------------------------------------------------------------------------------------

Failure: ERROR:add_1 must be in range [-1,DEPTH-1]
Time: 8900 ns  Iteration: 1
$finish called at time : 8900 ns : File "F:................v" Line 37
run: Time (s): cpu = 00:00:05 ; elapsed = 00:00:21 . Memory (MB): peak = 2102.461 ; gain = 0.000

--------------------------------------------------------------------------------------------------------------

The I switch the verfication tool to synopsys vcs-mx, and the simulation work well.

 But Why?
