title: Assign value to only one bit in a vector module output
body: <p>I have the following code and I get an error. I am trying to use only one bit out of the four lines in the inputs A, B, and the output, Y. To be clear, I do not want to use the AND operator, I want to use the AND module that I made.</p>
  <pre><code>AND_Gate_Quad_SN74AHCT08N and0(.A({3'bzzz,clk_disable}), .B({3'bzzz,clk}), .Y({3'bzzz,clk_buffer}));
  </code></pre>
  <p>What would be a good way to accomplish this?</p>
