  Analysis Program for Linear Active Circuits (APLAC) is a general-purpose
electronics circuit simulator, which has included a built-in model of the
Josephson junction (JJ) since late 80's. It capabilities in simulating eg.
noisy Superconducting Quantum Interference Devices (SQUIDs), Rapid Single Flux
Quantum (RSFQ) logic circuits, or Superconducting Transition Edge Sensors
(TESes) are relatively unknown within the superconducting electronics
community. Here we give a brief step-to-step tutorial for APLAC users to
unleash those capabilities.
