[IBIS] Mismatch between ibischk and load lines

Hello,

I am working on an IBIS Model and the golden parser (I have used 4.1, 4.2, and 5.0 and my model is IBIS 4.2) gives me errors (on the high side - pull up curve) on one of my outputs. I have independently verified the load line and where it crosses the PD and PU curves, and the crossing exactly matches my transient end values, and does not match what the parser is claiming the crossings are. What could I be doing wrong?

Best,

-Peggy
