So for the length thing we can't use the ctrl_ren signal because it actually comes after the read. We need to generate when we read out the ctrl_data.

Basically, we need to generate an SOP signal.

What is SOP? Its the first cycle we see TVALID after reset or TLAST.

You could make the sim shorter if you made the fifo smaller...

2^15 *4 is very large, thats a 128k fifo. we could change this to 16k

well we did have of the improvements, we can come back to them later.
