yylau, No. The requirement is not zero. The starting and ending points are determined by the IV curve / load line intersection, where the IV curve stands for all clamps and one pullup or pulldown IV table added together, and the Rfixture Vfixture combination of the waveform that is being investigated.

But I got 1 model with these 2 point far away from '0', and it still pass the ibischk3. So, do the model wrong or correct? And what will cause the points not start or end at '0'?
