Match font between \texttt and text inside lstlisting

Question

I am trying to match the font between the line that says: reg [8:0] data_saved [0:3]; // memory declaration

and the rest of the lines that are inside lstlisting. Here is what I get:

My code looks like this:

\documentclass [11pt] {article}
\usepackage{epsfig}
\usepackage{enumitem}
\usepackage{url}
\usepackage{epstopdf}
\usepackage{listings}
\input std-defs
\input EECE2323-header
\begin{document}
\noindent
\lab{3}{LAB3 - Arithmetic and Logic Unit Part II and Register File}

    \texttt{reg [8:0] data\_saved [0:3]; // memory declaration }

and then initialize its values with the \texttt{initial} declaration:


\begin{lstlisting}[xleftmargin=10em]
// Initialize Inputs Stimulus
initial
  begin
     data_saved[0] = 9'b000000001;
     data_saved[1] = 9'b000000010;
     data_saved[2] = 9'b000000011;
     data_saved[3] = 9'b000000100;
     end
\end{lstlisting}


\textbf{Use alu\_reg\_file\_tb.v as your Testbench template.}

\end{document}

But if I try to add \texttt to the lstlisting than I just see the word \texttt in the text.

Any ideas? Thanks!

You should have a \lstset instruction in your preamble:

\documentclass [11pt] {article}
\usepackage{graphicx}
\usepackage{enumitem}
\usepackage{url}
\usepackage{epstopdf}
\usepackage{listings}
%\input std-defs
%\input EECE2323-header

\lstset{
  basicstyle=\ttfamily,
  columns=fullflexible,
}

\begin{document}

%\noindent
%\lab{3}{LAB3 - Arithmetic and Logic Unit Part II and Register File}

    \texttt{reg [8:0] data\_saved [0:3]; // memory declaration }

and then initialize its values with the \texttt{initial} declaration:


\begin{lstlisting}[xleftmargin=10em]
// Initialize Inputs Stimulus
initial
  begin
     data_saved[0] = 9'b000000001;
     data_saved[1] = 9'b000000010;
     data_saved[2] = 9'b000000011;
     data_saved[3] = 9'b000000100;
     end
\end{lstlisting}


\textbf{Use alu\_reg\_file\_tb.v as your Testbench template.}

\end{document}

I have commented out the parts that I can't use (the two \input instructions and the line with the \lab macro), but for the rest I didn't touch the file, apart from changing the call to epsfig into the call to graphicx. The former package is obsolete and should not be used in new documents.
