fft_ip核仿真，接口时序问题

我使用的软件版本是2018.1 pro专业版 在对FFT IP核进行仿真时，对其时序产生疑问，请各位帮我看看，我输入的信号时序，哪里给错了，为何输出的source_error会给2b'11的值 IP核的配置如下 请求帮忙，卡了好久了，实在不知道哪里出了问题

Hi,

As I understand it, you observe some issue when trying to simulate with FFT IP. For your information, I have generated the example test bench using Q17.0Std mimic your IP configuration. I am able to run the simulation without error. I have attached the simulation files for your reference. You can try to look into it and cross check with yours to see if can spot any anomaly.

To run the simulation:

1. Open Modelsim and change directory to simulation_scripts\mentor

2. "source msim_setup.tcl"

3. "ld"

4. "do wave.do"

5. "run -all"

Please let me know if there is any concern. Thank you.
