    SKILL code to get area of particular layer Reply

    Hi friends,

    Can anyone help me out writing a skill code that will calculate the area of diffusion in a layout.The top level contains many instantiated blocks.So i have to take the layer fron those blocks also.the diffusion are of various shapes(path,rectangle,even in guard rings).

    Thanks and Regards,

    Hi Andrew,

    Thankyou that solution was quite helpfull.But i faced 1 more problem. 

    I am not able to flatten "mosaicInst" ,is there a way to flatten it.For mosaicInst it is giving error like:

    *Error* dbFlattenInst: invalid instId or mosaicId - <some dbid for mosaicInst>.

    1 more thing how to find the area if the layer forms a rectangular ring.

    Regards,

    Kashfi Israr

     Hi Kashfi,

    That solution doesn't use dbFlattenInst, so I'm not sure why you need that. You must be using IC5141 because mosaicInst objects only exist in CDB - these are component pieces of a mosaic rather than the mosaic itself, and you should not attempt to flatten them. Instead you'd need to find the mosaics from cvId~>mosaics - these can then be flattened with dbFlattenInst.

    Regards,

    Andrew.
