HI, 


 I am gettine the fallowing Errors from my Isim Simulator.

I am not getting any Output data from the Decoder. The s_axis_output_tdata Signal is always Zero because of the above error's. so Decoder is interpreting all the values into 0 for all the similation time. I have added the new package. so there is no compilation error just Simulation Errors.
