Two-Input OR Gate Using Only Two-Input NOR Gates

EasyLogic CircuitBuild

Standard cell libraries often restrict designs to a single universal logic family to simplify fabrication and layout. Deriving basic logical operations from a single primitive gate is a foundational step in technology mapping.

| A | B | Y | |-----|-----|-----| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 |

Constraints

  • Implement the circuit using only 2-input NOR gates.
  • Do not use standard OR, AND, or NOT gates.
