How to check abutment status

AshokDeEmperor

Hi,

In my layout I have few transistors abutted to each other. either my manual movement the automatic abutment happened or I have used spdPerformAbutment(inst1 inst2 0 "sdFirst") command to abut two devices.

I want to get db ids of the instances in my layout which are been abutted. how to check if a device is abutted to other device using skill.

please let me know how to do so using skill.

Thanks And Regards,

Ashok Kumar Mishra

    Hi Ashok,

    Try the following commands:

    1. geSelectAll() or you can manually select all the objects in the cellview. 

    2. setof(x geGetSelSet() x~>objType=="inst" && dbProduceOverlapInst(geGetEditCellView() x~>bBox))

    This will give you the list of dbIds of instances which has an overlapping instance or an instance at the boundary.

    I don't know whether this is a valid way of finding the abutted instances. But this can be used as an workaround.

    Thanks,

    Vijay

    Hi Vijay
    thank you for your reply.
    the command dbProduceOverlapInst(geGetEditCellView() x~>bBox) will list the instance not abutted but where implant region is overlapped. what I want to find is device id which is been abutted withpcell abutment feature.

    however I appreciate your quick help

    I don’t believe there is any public API to check whether abutment has occurred or which devices have been abutted. There is data stored (mainly to allow unabutment to occur), but there’s no public information to determine this that is public and safe to use. You should contact customer support to request something that does this.
