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

  • Andrew,

    Your suggestion  worked very well ,Thanks!

    As an experimtnt I also tried the following.

    moved the pcDefinePCell and CDF definition to a new file test1.il and auxillary function iCCScreateBoxAndLabels in t2.il

    First time, I started cadence and loaded t2.il manually, then loaded t1.il . The pcells were now created properly and I was able to instantiate them ok.

     

    I then closed cadence and added load t2.il in my .cdsinit file and started cadence. Again I was able to looat the pcell instances without problem.

     

     

    However when I tried to stream out again I get the same undefined function error. It looks like the strem out process doesnot read the .cdsinit file, is that correct? Also, it looks like strmout started from cadence does not see the auxillary function even if that function was manually loaded. 

     

    Thanks,
