模拟与混合信号电路的形式化验证
资料介绍
针对模拟与混合信号（AMS）电路形式化建模逼真度低和描述不规范的问题,提出一种基于基尔霍夫电流定律节点分析的形式化建模方法。通过扩展计算树逻辑公式,在保留电路更多物理特性的前提下综合描述和验证AMS电路的离散事件和动态行为,保证性质验证的精确性和可信性。以环形振荡器为例,给出该方法的实现过程,并通过Coho工具对振荡器电路进行验证。实验结果表明该方法正确、有效。
For the low fidelity and non-normative description of formal modeling in Analog and Mixed Signal（AMS） circuit, a formal modeling method is proposed based on nodal analysis of Kirchhoff＇ s Current Law （ KCL）. An extension to Computation Tree Logic （CTL） formula is developed to describe the discrete events and dynamic behavior of AMS circuit and reserves many physical characteristics of the circuit, which guarantee the accuracy and credibility of the properties＇ verification. Taking the ring oscillator as an example, it illustrates specific implementation processes of the proposed method and verifies the oscillator circuit by Coho. Experimental result shows that the proposed method is vaild.
