VIdeo Color Space Converter IP core

Hi,

I plan to use Clocked Video Input II + Color Space Converter II + Clocked Video Output II.

I generated these IP cores from Qsys with the associated testbenches.

I tried to simulate the design with modelsim and I noticed that data_out stream of the CVO-II is always XXXXX. Did someone simulate the CVO-II please?

Best regards,

Alexandre
