      if(member(sh1 gates) then
        dx1 = length(setof(i m (i < x1)))   
        dx1 = dx1 * inc_gate
        dbMoveFig(sh1 nil list(dx1:0 "R0"))
        chk=dbLayerSize(cv "POLY" list(sh1) 0.0075)
        ;dbLayerAnd(cv "POLY" list(sh1) list(chk))
        dbDeleteObject(sh1)
        )


           );foreach sh1



    In the Output Layout,there are many DRC violations i.e after stretching gate,same DRC's should be there..but that is not happening in my code.

    Please help me to improve my code/any new code such that polys's stretchs and DRC's are followed finally

    There are a few variables and functions in this that aren't defined, and also it's very hard to know what it will do without seeing the actual layout data (and a database would help, rather than a picture), unless I spend time coming up with a testcase - especially as there are (pretty much) no comments in the code.

    I can't tell what would cause DRC errors or not without knowing what your technology rules are.

    Please put yourself in the position of a reader of your post - and think about whether the reader would have to know information that's only accessible to you or whether they can infer everything from what you've posted.

    Regards,

    Andrew.

        if(member(sh1 gates) then ;sh1 is any shape
        dx1 = length(setof(i m (i < x1)))   
        dx1 = dx1 * inc_gate
        dbMoveFig(sh1 nil list(dx1:0 "R0"))
        chk=dbLayerSize(cv "POLY" list(sh1) 0.0075)
        ;dbLayerAnd(cv "POLY" list(sh1) list(chk))
        dbDeleteObject(sh1)
        )


    This is my code..sorry for the lack of clarity in the previous mail.

    I am working on 70nm and all the polys should be stretched to 85nm...and DRC rules like poly-poly distance and poly contact distance should also be same after stretching polys.BUT after execution of this code:is not same as the original layout.

    Andrew,

    You understood my code and you got some-through?

    And I have one more doubt...I want to reduce  each poly, left by say 5nm and right by say 7nm..like i want to reduce leff side of poly and right side of poly by some amount(here,poly includes polys of "polygon" and "rect" shape)

    Can i do this with leStretchShape?

    As I said, debugging your code without any data is quite hard, especially when your explanation of what you're expecting it to do is a bit vague. It's still not that clear to me precisely what you're expecting.

    Also, this forum is manned by volunteers - it's not a substitute for customer support. For example, I'm currently out of the office at an event - so if you want urgent support, please contact customer support - and you'll need to provide enough data to reproduce the problem (that would have been helpful here, as I mentioned earlier)

    Kind Regards,

    Andrew.
