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 Andrew. I started with top-down approach with skill rather then bottom-up.I thought it was easier way for me to learn skill coding.
What I mean by that is :I have written skill code that can generate array and labels from already layed out cell.
I had few questions regarding this :
Is there any way I can generate skill code from layout I have? I had this question because I wanted generic way for generating text from lower level layout cells on top level cells.
Eg : If I have x cell which has 10 - y cells arrayed.I want labels from y cells to be replicated at x level with _1,_2,_3 .
I know and I already did skill code for this but I need a standard way ( single code) that can do it for any cell array I want .This without hardcoding the labels and pins in my skill script.
For this reason wanted to check if there is some way I can generate skill code from layout of lower level.This way I can make my standard skill code point to skill code generated from layout to pass on the pins labels etc.
I am really struggling over making standard code for all the array combinations without having hard coded labels or pins.Please suggest me if you have any other better way or idea regarding this.
