Inserting errors for CRC checker

[Bruno8124]

Hi,
I am making a project using DE - 10 Standard kit. In this project, data is sent from one M10K block to another through a DDIO receiver/ transmitter. I want to do a CRC checker to check if the transferred data is valid. I have a question: how can I insert some errors in the transfer? I heard that mobile phones can distort this process.

Is there a way you can turn off the broadcast in mid-transmission? This assumes no harm can result.

Do you have a second kit? Can you turn on both transmitters simultaneously?

 

[Bruno8124]

Yes for all your questions.

Does your system report errors when transmission is interrupted?

Does your system report errors when a competing transmission interferes?

Part of transmission channel is hardware connecton through GPIO. My system reports that CRC is not valid if, for example, one pin of this connection is missing.
