How to access pcell instance co-ordinates from within Pcell code.

Jameel
Hi, Is there a way to find out the co-ordinates of the pcell instance from within the pcell code? Say for example, I want to create a pcell that prints a label showing the co-ordinates of the where the pcell is placed. within the code of the pcell I can create the label at the origin but i need to know the co-ordinates of the pcell instance in order to print the label. One way of doing this would be to pass the co-ordinate of the pcell instance as parameters, but am not sure if this is the correct way to do it. Thanks, -Jameel

  • Hi Jameel,

    Your question is a little imprecise, what do you mean by "co-ordinates" of the pcell instance, the bounding box co-ordinates, or the origin?

    Hopefully Derek's answer solves the problem, but if you were looking for the bounding box, you could access ilInst~>bBox instead, for example.

    The problem is that within the PCell itself, it knows its own origin as 0,0 but the instance origin could be anywhere when the pcell instance is placed, however the pcell (master/supermaster) has no knowledge of the "parent" cellview where it is being placed. Likewise for the cell's bounding box - within the cell's coordinate system it will be one thing, but when placed in a cellview, the instance's transform needs to be taken into consideration.

    I think Derek's answer should answer your question though.

    Regards,

    Lawrence.
