How robertgg3112/ldo-gf180 works
This repository is an analog-design workspace for an LDO using the GF180MCU PDK, accompanied by a script for installing the documented open-source toolchain. The intended workflow is to install the environment, create and simulate schematics, then work on layout and run design-rule checks and extraction; the README also documents LVS and layout viewing. The tree contains a characterization schematic and SPICE deck, but most project directories are placeholders. Relationships below follow the README; no source excerpts were available to verify implementation details.
