I am working on Cadence Virtuoso, and I am facing problem in making layout of pad and padframe of 40 pin IC. I am using gpdk180 library.
I want to make layout of an IC. And that IC will contain several circuits. I already made layouts of all those circuits. Now I want to integrate all those circuits in the form of a 40 pin IC.
I searched this on internet, and I got a tutorial of making layout of pad and padframe but he is using NCSU library. And he used pad layer, metal 3 layer and glass layer to make pad. But pad layer and glass layer is not there in gpdk180 library.
So, can you please tell which layers I have to use and what are the steps to make the layout of a pad of an IC using gpdk180 library..??
