Dear Sirs and Madams, 

i try to test CIC ip core. 

My parameters are: 

Input Sampling rate 120MSPS 

System Clock 120MHz 

Decimation rate 120 

Input Channels 16. 

 

Problem is core does not generate start of packet and end of packet signals(of course i have this signal i code). Also i see result on wrong channel. Can anybody say something about this?

My advice is to run simulation first of all, rather than using hardware captures. With sim you can follow events from the start while with hardware if a fault occurs anytime it will propagate through and gets hard to debug. There is also possibility of timing errors or fifos/rams getting out of control.
