How can we add pins so we can recognize the ports of the device?
Hi. Your repo mentions that for most of the devices are verified by "semi-automatic". Does that include automated LVS scripts that extract resistor/capacitor devices? It seems that I am unable to find how res/cap are extracted in your LVS script: https://github.com/mabrains/sky130_klayout_pdk/blob/main/lvs/lvs_sky130.lylvs
Thanks for the help.

@mohanad0mohamed Hello, Is it possible to let me know where did you find the gds files that you have here? I can't find these in the Skywater repository.
Our Magical team is currently working on supporting skywater-pdk to enable open-sourced tape out design. We have already finished the PMOS and NMOS device generation part, and are in desperate need of your support for the resistor and capacity LVS file to further boost the impact of both your open-sourced skywater-pdk and our Magical tool. Could you provide the resistor and capacitor LVS file? We also need parasitic extraction to generate the analog IC layout automatically.
Thanks for your help.
