Question

I'm not getting the expected results when running the IBIS model, any suggestions?  

Answer

Attached is a troubleshooting guideline, in summary

  • The DC bias points may have not settled, increase the time scale, e.g. 1-5 us/div, run the model, then decrease the time scale and adjust the delay time as needed
  • Optimize the matching circuit
  • Double check for missed connections

  • Timing
