摘要

VHDL-AMS，混合信号IEEE 1076.1标准建模语言，描述混合信号电路。模拟解算器与数字仿真核之间的同步是混合信号仿真中的一个重要挑战。本文介绍了一种用于混合信号仿真的算法，该算法减少了数字仿真核和模拟仿真核之间不必要的交互。为此，我们使用一个通用的数据结构，并消除了模拟内核对数字内核的调用。本文讨论了我们常用的数据结构、仿真过程和模拟/数字同步算法。用了几个例子来说明我们的性能改进。

A new synchronization algorithm for (VHDL-AMS) mixed signal simulation

VHDL-AMS, the mixed signal IEEE 1076.1 standard modeling language describes mixed signal circuits. Synchronization between the analog solver and digital simulation kernel is an important challenge in mixed signal simulation. In this paper we introduce an algorithm for mixed signal simulation that reduces unnecessary interaction between digital and analog simulation kernels. For this purpose we use a common data structure, and we eliminate invocation of the digital kernel by the analog. This paper discusses our common data structure, simulation process, and analog/digital synchronization algorithm. Several examples are used to demonstrate our performance improvement.
