Integrated Circuit Timing Simulation

研究的重点是电路时序仿真的类型，它可以进行可变精度的分析(由用户自行决定)。这种时序仿真方法有可能为设计工程师提供更快、更准确的电路设计仿真。这项研究正在进行一种名为SPEC82的集成电路时序模拟器原型的工作。该原型模拟器是基于树/链路的、事件驱动的，并使用电荷和能量守恒表模型来表征器件。在模拟的速度和精度方面都取得了可喜的结果。研究工作是通过容纳更多设备、通用宏建模、扩散时间常数控制和自适应误差控制来提高SPEC82的能力。基准测试将在改进的SPEC82模拟器上运行。

The research focuses on type of circuit timing simulation, which can do variable accuracy analysis (at the discretion of the user). This approach to timing simulation has potential to provide design engineers with faster and more accurate simulation of circuit design. The research is on-going work on an integrated circuit timing simulator prototype called SPEC82. This prototype simulator is tree/link based, event-driven and uses charge and energy conserving table models for device characterization. It has shown encouraging results in speed and accuracy of simulation. Research is in improving capabilities of SPEC82 through accommodation of more devices, generalized macro- modeling, spread time-constant control, and adaptive error control. Benchmark tests will be run on the improved SPEC82 simulator.
