VHDL- AMS是 VHDL 向模拟和混合信号领域的扩展 .VHDL- AMS为设计者提供了在概念级处理复杂系统的能力 .随着 VHDL- AMS的标准化 ,将诞生处理复杂的模拟和混合信号模型的有效的模拟器 .文中介绍了VHDL- AMS模拟扩展的主要内容 ,展示了一个混合模式模拟环境 ,并给出了模拟解算器的构成 ,讨论了连续和离散模拟的同步问题 ;用 4个例子说明 VHDL - AMS在概念设计中的应用 VHDL-AMS is an extension of VHDL to analog and mixed-signal VHDL-AMS provides designers with the ability to handle complex systems at the conceptual level. With the standardization of VHDL-AMS, there will be the advent of complex analog and mixed-signal models Effective simulator.This paper introduces the main content of VHDL-AMS simulation extension, presents a mixed-mode simulation environment, and gives the structure of the simulation solver, discusses the synchronization of continuous and discrete simulation; with four examples Explain VHDL - AMS in the conceptual design application
