Check the last modification date and time of GDS content

Will Tang

Hi all,

Is there any script or function in the menu bar to check the last modification date/time of GDS content?

(modification date/time of the last modified cell in GDS)

Thank you very much

Will

  • Hi Will,

    There are some capability within QuickView (the k2_viewer program in the PVS stream), including an ASCII dump of GDS - see QuickView 015 ASCII Import/Export. However, this only appears to be available through the UI and none of the batch programs dump out the modification date from the BGNSTR record.

    Of course, you could write your own using C code (I've done similar things in the past, but never to dump out the modification date from each structure).

    So I don't think there's a Cadence utility or script to do such a thing. I did just do a google search for "python program to read GDSII" and here's one such library of functions that might help: https://pythonhosted.org/python-gdsii/ 

    Regards,

    Andrew
