Alaa,
Your IV curves may have the opposite polarity. I am
saying this, because the parser's IV curve and load line
solver solves for negative voltages for the rising edge.

Subject: [SI-LIST] ibis check output errors
Hi Guys,
can anyone help explain why the ibis checker is reporting these huge
differences between the I-V curves and V-t curves. I checked the =
transient
response of the buffer and it looks good. Is it something to do with
tolerance or range of voltage?=20
Any help would be greatly appreciated.
Thanks,
Alaa Alani
here 's the ibis checker output:
