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.
I forgot to mention that the stretch handle visibility can be controlled by the user from the Options->Display "Stretch Handles" toggle, which may be off by default.
