一句话：提出复制辅助分区的并行 RTL 仿真方法，降低通信同步开销并实现超线性加速。
RTL 仿真在硬件设计开发、调试、验证与确认中不可或缺。尽管硬件本身具有并行性，现有并行 RTL 仿真器因典型电路拓扑导致的高通信与同步开销，难以获得实用加速。本文提出 RepCut，一种复制辅助分区（replication-aided partitioning）方法，通过复制关键电路部分来改善并行划分，从而减少跨分区通信和同步需求，使并行 RTL 仿真能够获得超线性加速。标题与摘要表明该方法针对通信和同步瓶颈，目标是在硬件设计上提升并行仿真速度；具体实验评估未在摘要中展开。
Register transfer level (RTL) simulation is an invaluable tool for developing, debugging, verifying, and validating hardware designs. Despite the parallel nature of hardware, existing parallel RTL simulators yield speedups unattractive for practical application due to high communication and synchronization costs incurred by typical circuit topologies.
