Hi forum posters, I tried to find the previous threads on [Submodel] and [Add Submodel] keywords to no avail, so here I'm posting yet another question. I understand that I have been posting questions a lot lately, so bear with me if anyone is getting bored with me spamming the forum. I have another two questions: 1. I find the [Submodel] and [Add Submodel] keywords very useful in shrinking the IBIS models file size. Assuming an IBIS models file containing 100 models and all sharing the same [Ground Clamp] and [Power Clamp] data. In this case, I can reduce the file size by using the keyword [Add Submodel] to refer to a [Submodel] that contains these [GND Clamp] and [POWER Clamp] data, thus avoiding to repeat the [GND Clamp] and [Power Clamp] data for each model for 100 times. While I manage to reduce the file size of the IBIS models by ~20%, is this technically the correct usage of the keywords? What does it exactly mean by a "Dynamic_clamp Submodel"? 2. I understand from the IBIS spec that the keyword [Test Load] was used to derive the golden waveform. Will there be a problem if define the [Test Load] keyword with the respective electrical parameters such as Rs_near, Vterm, Rp1_near on my driver without defining the [Test Data] keyword as well as not having a golden waveform for that IBIS model. This doesn’t prompt me any warning when I perform the syntax check but I’m worried that this could be technically wrong as well. Please advice.
