title: What does "quality of result (QoR)" cover?
body: <p>The vendors of EDA tools for HDL design and simulation are increasingly using the term <em>quality of result</em> (QoR).
  Especially when it comes to <em>high level synthesis</em> (HLS) for FPGAs the term is used in inflationary numbers, without prior definition.<br>
  But how is QoR defined? Is QoR a metric for a piece of HDL code or a metric for the performance of an EDA tool?</p>
  
  <p>--</p>
  
  <p>The QoR article on Wikipedia does only give a very brief description, mainly about the historical origins of the term, i.e. QoR was used from the 1980s onward to characterize a chip design in terms of silicon area, power consumption &amp;cetera.<br>
  Nowadays the terms seems to be used in a more general sense. Also, it sounds like a generic yet fancy way of expressing that A is better than B <em>somehow</em>.  </p>
  
  <p><sub> I am consciously taking the risk that this question may be considered "too broad", but imho that will just mean that no concise definition of the term QoR exists...</sub></p>
