超导电子学(SCE)运行在数百GHz,仅消耗CMOS动态功率的一小部分,但本质上是基于脉冲的,并且工作在皮秒宽度的脉冲上。这些操作的瞬时性需要使用固有地有状态的逻辑单元。 然而,采用有状态门意味着设计、仿真和验证堆栈的整个重建。虽然具有挑战性,但这个独特的机会使我们能够使用编程语言设计的基本原则从头开始构建设计框架。 为此,我们提出了PyLSE,一个嵌入式脉冲传输级语言的超导电子。我们通过基于转换系统的形式化语义定义了PyLSE,并围绕它们构建了一个框架来模拟和分析SCE单元。为了证明其功能,我们验证了它的结果通过模型检查UPPAAL,并比较其复杂性和时序对一组单元设计为模拟电路原理图和模拟Cadence。
Superconductor electronics (SCE) run at hundreds of GHz and consume only a fraction of the dynamic power of CMOS, but are naturally pulse-based, and operate on impulses with picosecond widths. The transiency of these operations necessitates using logic cells that are inherently stateful. Adopting stateful gates, however, implies an entire reconstruction of the design, simulation, and verification stack. Though challenging, this unique opportunity allows us to build a design framework from the ground up using fundamental principles of programming language design. To this end, we propose PyLSE, an embedded pulse-transfer level language for superconductor electronics. We define PyLSE through formal semantics based on transition systems, and build a framework around them to simulate and analyze SCE cells digitally. To demonstrate its features, we verify its results by model checking in UPPAAL, and compare its complexity and timing against a set of cells designed as analog circuit schematics and simulated in Cadence.
