## Overview

Logi7400 is a Logisim component library for designing logical circuits and for education. A designer uses Logisim and selects components from either the classic DIP-layout library or the logical-appearance library. The README documents gates, inverters, sequential components, encoders/decoders, and arithmetic/counters as capability areas. No source excerpts were provided, so the graph shows only relationships documented in the README; it does not infer internal circuit wiring or claim that the two library files share implementation code.

Main entry points: [`logi7400dip.circ`](https://github.com/r0the/logi7400/blob/master/logi7400dip.circ) (DIP library), [`logi7400ic.circ`](https://github.com/r0the/logi7400/blob/master/logi7400ic.circ) (Logical library)
