title: Compiling *.vhdl into a library, using Altera Quartus II
body: <p>I am trying to use 'Floating point and Fixed point package' as a part of my filter design in VHDL. I am using Altera Quartus II as the development environment. I downloaded the file package from the website: <a href="http://www.vhdl.org/fphdl/" rel="nofollow">http://www.vhdl.org/fphdl/</a>, now available at <a href="http://web.archive.org/web/20160305202256/http://www.vhdl.org/fphdl/" rel="nofollow">http://web.archive.org/web/20160305202256/http://www.vhdl.org/fphdl/</a></p>
  
  <p>In their user guide, below is mentioned:</p>
  
  <pre><code>'fixed_float_types_c.vhdl', 'fixed_pkg_c.vhdl' and 'float_pkg_c.vhdl'
  should be compiled into a library called "ieee_proposed".
  </code></pre>
  
  <p>However, I do not exactly know how I can compile the mentioned *.vhdl files into a library using Altera Quartus II tool.</p>
  
  <p>Any tip would be appreciated.</p>
