Skill code to evaluate all components area (Accumulative Place bound area)

Hi I am starting a very small and dense design with many 0.5mm BGA's with BBV,About 1000 comps. I am afraid that the total available PCB area for component placement is not enough. Is there out there any Skill that sums up all components place bound area ? So I can compare it to board’s available placement area ? and not end up placement with components left outside the board ;-) BTW : There is a similar function inside the Mentor Expedition. Best Regards Roby

Hi.
I have code that gives the absolute areas of top and bottom components and the ratio of board usage using the board outline - if it is a contiguous shape. I will need to take a minute to convert it into public code - if you still want it.
Regards,
Dave

See attached. Installation instructions are in the header.
This cut down version for public release is very basic. It doesn't allow for cutouts or other restricting features. It will, however, ignore placebound shapes with a PACKAGE_HEIGHT_MIN property > 0 (shields etc).

Dave

Hi
I don't know if you want it, but I have created some code that reports the size of shape bounds on each psm file in the psmpath. I've seen a number of users embed that code into their component database for area requirement calculation as part of the BOM generation at any point during the design phase.
The zip file contains a pdf document that describes the functionality. The skill file is currently encrypted due to embedded custom code, I'll possibly remove that code if it is easy to do so.
Let me know if this is something that can be used?
Best regards
Ole
