6.2 Error Signaling and Logging（错误信号与记录）原文第1句（Page 11）In this document, errors which must be checked and errors which may optionally be checked are identified.翻译本文档中，定义了必须检查的错误和可选择检查的错误。SoC集成角度解释规范将错误分为两类：强制检测（所有实现PCIe的设备都必须检测）和可选检测（取决于实现）。作为SoC集成者，需要查阅具体表格（Table 6-2到6-5）确认哪些错误是强制的。例如：Malformed TLP是必须检测的；某些内部错误是可选的。设计时需确保PCIe IP配置了必要的错误检测逻辑，并能够上报。原文第2句Each such error is associated either with the Port or with a specific device (or Function in a Multi-Function Device), and this association is given along with the description of the error.
