Walter, I'm not sure who Nicklas is but I'm one of the authors of the Golden Standard paper. Section 1.4 only talks about the theory. Section 1.5 is the beginning of the simulated results. I make reference to a "SPICE simulator" and maybe I should have been more clear on that. It certainly wasn't meant to confuse or mislead. We used Hspice for simulation for all of our models. Our goal was to take all of our software packages in house and generate as many possible models in every possible way. We would take these models and run them through Hspice to generate results. We consider all of the Hspice results to be our simulated results and will be posting these results on our website in the up an coming weeks. It will provide a table that will show all the results of the various models and talk a bit about why the inconsistencies occur. This is also the point where we hope everyone will join in the discussion and add their results. That's the real goal.

I have just subscribed to the si-list and I have not yet understood how to address a replay to a previous message. I have read the part 2 of the golden standard paper which explains the theory behind the proposed test kit and gives some comparison between the analytical, simulated and measured curves. It is not clear to me what are exactly the simulated ones. I have understood that the analytical curves are derived from the propagation characterisics of the even/odd modes and tha ts is ok to me. Section 1.4 of your paper speaks of a spice model but it is not explained how it is generated. It is also said that the spice simulations have been compared with those of separate numerical solver but this data is not shown in the curves. So my question is: what is the meaning of the difference between the analytical and the simulated curves. If the latter are all related to the spice model, to appreciate the difference you should explain how it has been generated and correlate the difference with the approximation s made in this process.
