Abstract

Standard gate and switch level simulators are not capable of simulating accurate behavior of certain properties of BiCMOS digital circuits such as bidirectionality and charge sharing. Therefore, the parallelizing and mixing of timing level simulation and gate level simulation within a multilevel simulator would provide an effective balance between simulation speed and functional accuracy. The ability of the simulation system to change its internal partitioning during simulation time is presented. This feature is called dynamic repartitioning and improves the speedup of parallel logic simulation about 20-40% using small numbers of subsimulators.<>

包括动态重分区在内的分布式多层逻辑模拟器中的分区策略
标准的门电平和开关电平模拟器不能准确模拟BiCMOS数字电路的某些特性,如双向性和电荷共享。因此,在多电平模拟器中并行化和混合时序级仿真和门级仿真将在仿真速度和功能精度之间提供有效的平衡。提出了仿真系统在仿真过程中改变其内部划分的能力。这种特性被称为动态重分区,使用少量子模拟器可将并行逻辑仿真的速度提高约20-40%。
