How to get " the rotation & coordinate to the top " of the cellname in a large layout design ?

Charley Chen

Dear All,

I want to get  " the  rotation & coordinate to the top " of the cellname in a large layout design , but how to do it ?

The cellname maybe has more than one  and the layout design is very large .

Thank you,

Charley

  • Charley,

    I still don't understand. If I open libA/TopCell and then do:

    CCFfindInstLocation(geGetEditCellView() ?cellName "targetCellName")

    then I get the coordinates/orientation of the instances of targetCellName relative to libA/TopCell. I just tested this (again). I don't know what you mean by "The coordinate of the targetCellName is for Lib C" - if that was the case, it would be 0:0 "R0" (if I've understood you correctly). So I really just don't understand what you are talking about.

    Could you (maybe) prepare a small database (with layouts that only use the "text/drawing" layer purpose pair) to illustrate what you mean and then post it here? Then provide the exact SKILL call you are making and what is wrong with the results?

    There may be something wrong - I just don't understand what you're saying.

    Regards,

    Andrew.
