Thank you. I tried your design, but I get always the same problem. I attack the simulation waveforms. As you can see the deinterlacer starts the frame acquisition and sends the control packet with dout_valid (cyan), but after lowes the din_ready (yellow) and stops the frame acquisition. What could be the probem?

Hi, As I tested running the simulation zip shared to you, the simulation seems to run OK as shown in the following screenshot. The din_ready is asserted to backpressure the TPG and then assert again when it is ready to accept data. Please feel free to let me know if you are not seeing the din_ready assert at later stage of your simulation or if you are observing differently. Thank you.
