ayow New Member Offline Posts: 1	Model QA Mar 02^nd, 2006, 5:43pm I would like to build up an in-house model QA ability for my Lab. The model issues we usually have are in-continuity, difficult convergence and in-accurate in some W/L region..etc. Could anyone share your idea about model QA process ? Thanks a lot. Ayow

If you want to see some documentation regarding compact model Q/A, you could visit www.eigroup.com/cmc Hope this help! Paulin

MQA automates a lot �of the hand check stuff, but I was not super impressed. They had a booth at DAC this year.

Here are a list of common model problems:

Read the list down under the foundry model audit stuff.
That is a list I developed from one pass at a single CMOS (it was 0.13 ) foundry.

IBM, Jazz, TI, National, ST Micro get their models right, �:) the rest of the world can be debated. �:-/

Lots of issues as you can see.

Its name is ModeLoo developed by SeveTek Inc. in Taiwan. (www.sevetek.com) I suggest you could try to contact with them for further information if interested.

Here is my "poke and sniff" method: http://www.chipdesignmag.com/display.php?articleId=438&issueId=16 That approach is not rocket science, but more common sense than anything. Jerry
