Abstract

Nowadays, the design of applications based on smart systems requires the joint simulation of both digital and analog aspects. Even if analog-mixed-signal (AMS) extensions of hardware description languages are an enabling factor, they do not provide a general methodology for the integration of AMS models into digital virtual platforms. This paper defines the problem and provides two main contributions: 1) the automatic conversion of analog models from Verilog-AMS to C++/SystemC, to remove the overhead of co-simulation with traditional virtual platform tools, and 2) the automatic abstraction of analog conservative models, with the goal of increasing simulation speed. Experimental results show that the virtual platform with automatically integrated analog components is 40 times faster than co-simulation with Verilog-AMS, and the increase of speed due to abstraction is more than 100%.
将混合信号组件集成到虚拟平台中,用于智能系统的整体仿真
目前,基于智能系统的应用程序设计需要数字和模拟两方面的联合仿真。即使硬件描述语言的模拟混合信号(AMS)扩展是一个使能因素,它们也不能提供将AMS模型集成到数字虚拟平台中的通用方法。本文对问题进行了定义,并提供了两个主要贡献:1)模拟模型从Verilog-AMS自动转换为c++ /SystemC,以消除与传统虚拟平台工具协同仿真的开销;2)模拟保守模型的自动抽象,以提高仿真速度。实验结果表明,自动集成模拟组件的虚拟平台比与Verilog-AMS联合仿真的速度快40倍,并且由于抽象而使速度提高了100%以上。
