摘要

本文概述了一种将关键系统需求形式化并将其分解为系统组件需求和最小(可能是空的)同步需求集的方法。通信顺序过程(csp)的跟踪模型是形式化方法的基础，EHDM验证系统是机械化证明的基础。最后讨论了该方法在字符检测中继器顶层实现中的应用结果。将中继器的关键需求分解为其各部件的需求。如果组件满足其派生要求，则中继器已被证明满足其关键要求。

Using CSP to develop trustworthy hardware

An overview of a method for formalizing critical system requirements and decomposing them into requirements of the system components and a minimal, possibly empty, set of synchronization requirements is presented. The trace model of communicating sequential processes (CSPs) is the basis for the formal method, and the EHDM verification system is the basis for mechanizing proofs. The results of the application of this method to the top-level implementation of an error-detecting character repeater are discussed. The critical requirements of the repeater are decomposed into the requirements of its components. Provided that the components meet their derived requirements, the repeater has been proven to meet its critical requirements.<>
