The proble of testbench

Question

Hi!

I am a newbie of the testbench,during the learning I meet some problem.

There is something wrong with the "dataout/=i",maybe they are different type.

what should I do to convert them into the same type?

please help me.

You can't compare a std_logic_vector with an integer. Use the 'unsigned' type from ieee.numeric_std instead
