could you help me about this vhdl error

I take this error after simulating this code: can't find a pinstub/port in the symbol, function prototype, or other construct 'test' that represents a design file that corresponds to pin XA2 in the file.

this is a 16 bit CSA simulator

Thank you for help

The code is Below :
