Toffoli reversible logic tile

Universal 3-bit reversible gate (CCNOT) implemented as a sky130 tile. Energy-bounded computation primitive; foundation for adiabatic / reversible / quantum-classical hybrid designs.

Faux-moat bypassed

Reversible logic is well-published academically (Bennett, Toffoli, Fredkin) but no public sky130-ready hardened tile exists. Researchers build their own from gates each time.

Value to customer

Drop-in reversible computing primitive. Compose into reversible adders, multipliers, and energy-bounded compute engines.
