Hello Peggy,
as Arpad pointed out, there might be many reason that causes the ibischeck message.
but please be aware, that the checker is using the sum of the static curves .
so for High : [pullup] + [gnd clamp] + [power clamp]
and for Low : [pulldown] + [gnd clamp] + [power clamp]
regards
Eckhard

Subject: [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
