VIP SCALER II output data all zero

When I run the SCALER II with no control port, I use the bicubic way. And I have no .mif file

The control packet can output correctly, but the video packet output is all zero.

The valid, ready, sop and eop are output correctly.

My datapath is as follows: deinterlace II --> CLIP --> SCALER II --> FRAME BUFFER

Can anyone help me to solve this problem, thanks

    Hi Jiangsuren,

    You will get the zero video packet out in the simulation could be due to the *mif file is missing.

    Could you please copy the coefficient .*mif file to your simulation directory from the following folder?

    \synthesis\submodules\src_hdl

    Please also check if there is any warning or error message from the simulation.

    Best Regards,

    Terence
