It seems there is some bug for the FIFO IP. I am using the quartus17.1 PRO version, the device is Stratix10 1SG280LH3F55E3VGS1. Please help to double check the issue.

Another fifo,input and output width is 32bit,depth is 8192.

Sometimes the fifo can not work well ,it is random.

But the depth set to 256, it is always ok.​

If mixed option fifo,there is some bugs.

I try to generate one FIFO, input data width is 32bit, output data widh is 256,and depth is 8192 words.

And the fifo can not work well,it can not read the correct data.

If the depth is set to 256, then the fifo is ok.
