摘要

我们提出了一种新的事件驱动仿真方法,该方法不使用集中的运行时事件队列,但能够处理任意模型,包括那些具有未锁定反馈和非单元延迟的模型。消除事件队列可以显著降低运行时开销,从而加快模拟速度。我们已经在一个名为VeriSUIF的Verilog模拟器原型中实现了我们的算法。使用这个模拟器,我们在一小部分程序上演示了与商业模拟器相比性能的改进。

A General Method for Compiling Event-Driven Simulations
We present a new approach to event-driven simulation that does not use a centralized run-time event queue, yet is capable of handling arbitrary models, including those with unclocked feedback and nonunit delay. The elimination of the event queue significantly reduces run-time overhead, resulting in faster simulation. We have implemented our algorithm in a prototype Verilog simulator called VeriSUIF. Using this simulator we demonstrate improved performance vs. a commercial simulator on a small set of programs.
