## Overview

This repository appears to be a Tiny Tapeout hardware project centered on differential-amplifier designs, with Verilog project configuration alongside analog schematics, SPICE files, and physical-layout artifacts. The README documents a configuration-to-Verilog project setup, but provides no details on how the analog designs relate to the Verilog or to one another. With no source excerpts, the graph shows the identifiable design artifacts without asserting unsupported calls or data flows.
