title: GPIB simulator (alternative to PyVISA-sim)
body: <p>While coding, it is not always easy to have a connected instrument via GPIB.
  Python offers the possibility to simulate an instrument using PyVISA-sim.</p>
  
  <p>Unless I am mistaken, the community is not really active, and I got several errors:</p>
  
  <p>1- PyVISA-sim gives a large panel of "virtual" instruments, but only one can effectively communicate with my code</p>
  
  <p>2- While creating my own .ymal file, python fails to recognize it</p>
  
  <p>I was wondering if there is an alternate way? </p>
  
  <p>I will be more greedy: is there a GPIB simulator that can also simulate an instrument response?</p>
  
  <p>For example: while simulating a voltmeter, the virtual instrument will effectively return me some "random" readings.</p>
  
  <p>The goal is to check if my Byte to Single converter is working properly</p>
  
  <p>Thanks</p>
