Recently, power dissipation is becoming a dominant factor in choosing the next technology. For this reason, most figures of merits currently used to test the potential of a given technology to be the next leading technology in the industry are Operations/Second x Watt or Joule/bit….and not just Operations/Second.
Superconductivity is the phenomenon in which we have zero DC resistance and is viewed as a technology capable of achieving better energy efficiency than any other. Superconductive circuits are based on the quantization of magnetic flux to a single flux quantum (SFQ) Φ0 = ℎ/2 = 2.067 × 10−15 [Wb]. The information passed in superconductive circuits are voltage pulses which are ≈ 2[picosecond] wide and ≈ 1mV high which constitute the passing of an SFQ. Superconductive logic circuits can be extremely fast and energy efficient. Circuits were tested operating in frequencies exceeding even 100[GHz].
In this project, the students will be introduced to the superconductive phenomenon, the Josephson Junction, an active device used to build circuits. The goal is to implement a Veriloga model of the device and and use it to implement test circuits in the standard superconductive logic family known as Rapid Single Flux Quantum (RSFQ). Simulations will then be performed to measure the speed and energy of the circuits. The results will then be compared to the performance of current technologies.
