Problem with FIR II core

Hello, I am trying to use 11 taps symmetrical FIR using the IP Catalog in Quartus 14.1 My data are in signed Q.15 format with sampling rate 288MHz. I get the data in packets of 4 samples (...

OK Now I have 288MHz clock to my FIR filter but I seems to get issues with it.

I have verified that filter 'valid' signal is constant 1 and filter output error[1:0] is 2'b00

Is this a confirmation that the filter manages to do its calculations on time?

What is to be expected if the clock reaches the filter maximum performance speed?

Thanks
