基于CHS软件的潜在通路分析方法

A Sneak Circuit Analysis Method Based on CHS Software

摘要:

针对传统潜在通路分析充斥着大量的手工操作，效率低下，而且还存在着分析周期长、自动化水平低和错误率高等问题，提出了基于Mentor Graphics公司CHS(Capital Harness System)软件的潜在通路分析方法，只需按照仿真步骤依次建立电气元件模型、构造功能约束，即可自动进行潜在通路遍历与分析。与传统潜在通路分析方法相比，该方法不仅减少了重复性操作，同时在降低系统复杂性、提高系统分析结果正确性和增强数据管理规范性、一致性等方面具有明显优点。以某运载火箭配电图为例，利用CHS软件开展潜在通路分析，仿真结果验证了该方法的正确性和可行性。

Abstract:

The traditional sneak circuit analysis were full of manual operations, low efficiency, and there were problems such as long analysis cycle, low automation level and high error rate. The sneak circuit analysis method based on Mentor Graphics' CHS (Capital Harness System) software was proposing, which could perform sneak circuit traversal and analysis automatically simply by following the simulation steps to build electrical component models and construct functional constraints. Compared to traditional sneak circuit analysis, this method could not only reduce the repetitive operations, but had obvious advantages in reducing system complexity, improving the accuracy of system analysis results, and enhancing the standardization and consistency of data management. The validity and feasibility of the method has been confirmed experimentally in the power distribution diagram of a launch vehicle by using CHS software.
