title: ModelSim PE Student Edition 10.1c (STD_LOGIC error)
body: <p>I am trying to use STD_LOGIC in my VHDL code. It will not compile because the STD_LOGIC I am trying to use in the <code>port(.....)</code> section is not working. I know the problem is because I did not import the IEEE library. I tried to import it but I was not successful. </p>
  
  <p>How to import the IEEE library properly to a VHDL program in ModelSim?</p>
