Hi Kaz,

I have one more issue :

I'm using a FIFO IP with width of the fifo being 16 bit and the depth of the fifo buffer is 16384 words. I'm using the MAX10 development kit and interfacing it with Matlab. The baud rate is set to 115200 bps. Data is being written in the fifo buffer continuously and when I send read command from matlab, data is being read from the fifo buffer. It happens sometimes that the fifo buffer is getting emptied at a faster rate than data being written into it and my matlab program terminates. Can anyone please help me with this issue.

Thanks
