pCell skill for beginners

stuso

Hi,

i'd like some advice for creating my first simple pCell from skill. I have no skill experience so i'm looking for a good place to start.

My ultimate aim (for now) is to create a rectangular via array with X and Y stretch handles. For example you have M1->M4(the top & bottom layers would be parameters) that you can stretch in X or Y and it fills with the max vias allowed by spacing rules. However to begin with i'd be happy to create a parameterised rectangle of M1 that i can stretch in one direction & take it from there.

Pointers to on-line tutorials and very simple examples would be great, right now i am blindly searching around source-link.

Thanks

Stu

     Hi Stu,

    You will need to create a library named "test" so that when the code is loaded the libraryId is found and then used to create the "encapRodPcell" cellview in that library.  The library should have technology information in it, for example, the "metal1" "drawing" layer is used in this example. There is a sample techfile in <cds_install_dir>/tools/dfII/samples/techfile/mpu.tf which contains this layer if you don't have a ready example to play with.

    Hopefully this will help you get started.

    Cheers,

    Lawrence.
