Hello All, I was referring to a old discussions on non-monotonicity and collected information that says these warnings are common for the Pullup and Pulldown tables in I/O. If the IBIS file version is used 4.0 or higher, many these warning could be removed which actually worked for IO. In my case, the pulldown and pullup data are non-monotonic and if i construct an Output type model which does not has Clamp data and therefore, the non-monotonicity will always exist. I'm attaching a section of pulldown/pullup data, please review it. I think after -0.9, the behavior of data is good but problem exist before that. Do you think that initial few non-monotonic data could create any problem? Thanks Mithlesh -- ---" "----------------------------" "--. Mithlesh Shrivas (Core-id:R64034).......
