VHDL-AMS中断列表的模拟方法

Simulation Method for Break List of VHDL-AMS

VHDL AMS语言支持连续系统和连续 /离散混合系统的描述与模拟 ,其中新增加的中断语句用于描述连续系统出现的不连续性行为 分析了目前模拟器在中断语句的中断列表的模拟方面存在的问题 ,提出用列方程计算与直接计算的结合法求解预定义属性Q’dot,Q’integ的解决方法

VHDL AMS language supports the description and simulation of continuous and mixed continuous/discrete system In the language, break statement is added to describe discontinuity appearing in continuous system This paper analyzes the problem found in actual simulators for simulating break list of break statement, and presents to it a solution for calculating the pre defined attributes Q'dot, Q'integ by combining the equation method and the direct evaluation method Finally, the correctness and efficiency of the solution are validated by simulation examples
