Calibre error : Cell *...* referenced but not defined.

[research235]

Hi

i am working at the final stage verification and wen i run drc on this gds2, I calibre ends with exit error and says.

error : Cell *...* referenced but not defined.

I have some 100s of this errors. can some one tell me .. wat could be the possible mistake i am doing

thank you in advance

Re: calibre error

This is a clear case of not giving GDSSII file for some (which are giving errors) cells which are present in design but not in GDSII.

Solution is, either merge GDS of all cells/macros/blocks OR specify GDSII files for cells/macros/blocks in caliber run

Re: calibre error

is there a database for the calibre errors, to find out more about their explanations and how to correct them in the layout..?

Re: calibre error

Hi,

If you are taking the cells from different libraries,make sure all libreries are defind in cds.lib or not.
If you take a cell from one library,if it is not defined in cds.lib,eventhough you can export GDSII you can't run any calibre runs.

hi salma,

if u work in more than 2 projects as physical verification engineer and if u can solve the errors. I bet after 2 projects ur able to understand the most calibre errors. So next time note the prob and how u solved it .. later this will help u .. so only exp helps u understand completly

you're perfectly right...it's by experience...it was all horrible and messy in my first design, then in the second one i knew directly what to do...so hopefully in the third one i won't have any errors to start with
