iic-jku/ihp-sg13g2-ams-chip-template ? reverse-engineered prompt

Build me a complete open source analog mixed signal chip template and tutorial for the ihp sg13g2 process, so someone can clone it, open it in the recommended container, and run the full flow without guessing.

I want the project to include a working top level chip assembly, a simple padframe, example digital and analog blocks, schematic and layout views, simulation and verification setup, and clear documentation that explains the pinout, floorplan, and how to get from specs to a tapeout ready result. It should also include a small regression style example that proves the flow works, plus generated layout and render outputs for the finished chip.

Please make it feel like a real starter project for beginners, with practical tutorial style docs and sensible defaults. If you need current tool details, look them up online.
