looking for Low latency IPcore suggestion for Stratix V GT

Hello Everyone,

I am using Low Latency Ipcore to tranmist from 4 channels, I define these datas as constant arrays.

When all 4 channel has the same array to transmit it works fine however when I change one of them to another data it effects all channels.

(For example I am scoping channel 1 and change the data in channel 2, channel 1 noise level changes -becomes worse.)

I couldnt find why? Any suggestions to find a solution?

Any help will be appreciated.

Best
