What is a manufaturing grid ?

NAADHAN over 16 years ago

Hi All,

Can anyone explain me what is a manufaturing GRID & its significance in our design?

Thanks & regards,

Hi Naadhan,
The manufacturing grid is the smallest resolution of your technology process. The value can be found in the tech lef file, for example:
MANUFACTURINGGRID 0.005 ;
but I always double-check with the sign-off DRC deck to make sure this is correct. Any shapes created in your design must align to this grid, otherwise you will get DRC errors.
