Error (10522): VHDL Syntax error at car.vhd(55): This error is caused by an unexpected end-of-file. The expected characters are "end", "(", an identifier, or a concurrent statement. Here is the problematic line

   car_inst : car port map (input_a, input_b, output_c);

This error occurs when the VHDL compiler reaches the end of the file and expects to find more code to execute. To fix this issue, ensure that all code is complete and there are no missing components, such as an "end" statement or close parenthesis.

Here is the HTML-formatted error message:
