Place cell and align to upper hierarchy object

Marios Barlas

Hello,

I am trying to create a mask layout for custom memory elements. I have created my memory cells using rod objects. Now I need to place them in the chip. To do that, I have thought and tried to implement the following: 

create an array of named rectangles then replicate and align my memory cell with each of these subrectangles. As I am using skill for less than two weeks, I have not managed to find in the documentation how to find an identifier for each subrect of the array. 

So far I have managed to pick the subrect names in a list. What is the right command to instantiate in skill my already made cell so that I can manipulate it later ? It is a cell of ROD objects thus I would like to think at least that a bounding box will be created and i will be able to use the same RoD handlers in rodAlign to align. Or do I need to make it a rod object first?

Is it possible to use the subrectArray to place my cell instead of a subrectangle directly?

Could some1 give me some directives ?

  • I'm not sure this is possible, because the sub-rectangles are not ROD objects in their own right. I guess you could use rodUnName to unname the multi-part-rectangle (or path) and then rodName each of the sub-rectangles? Or rather than creating sub-rectangles, you could use rodCreateRect to return a list of rod objects, one for each rectangle (see the documentation for rodCreateRect)?

    Regards,
