摘要： A method and apparatus for ensuring efficient validation coverage of an architecture, such as protocol or interconnect architecture, is herein described. A coverage space of states for an architecture is generated and stored in a database. During simulation, states of the coverage space encountered are marked. From this, the states encountered and not encountered may be determined. Based on the states not encountered, a targeted test suite is developed to target at least some of the states not encountered during previous simulation. This feedback loop from simulation to refining of a test suite based on states of a coverage space not encountered during simulation may be recursively repeated until adequate validation, i.e. an adequate confidence level of validation, of the coverage space is achieved.

摘要： Systems and methods of retraining a receiver provide for determining a minimum transition density for a derived clock data link to the receiver. A retraining flit is generated based on the minimum transition density. In one approach, the retraining flit is generated by defining control data and payload data for the retraining flit. Error detection data is determined for the retraining flit based on the control and the payload data. The control data, the payload data and the error detection data have sufficient transitions to meet the minimum transition density.

摘要： Multiple initialization techniques for system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible system/socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small server, large server, etc., as well as the component types such as IA32/IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated. For example, the POC values could be from the following: Platform Input Clock to Core Clock Ratio, Enable/disable LT, Configurable Restart, Burn In Initialization Mode, Disable Hyper Threading, System BSP Socket Indication, and Platform Topology Index.
摘要翻译：讨论了用于系统和组件在点对点架构中的多个初始化技术。因此，这些技术允许根据平台（如桌面，移动，小型服务器，大型服务器等）的需求以及诸如IA32 / IPF处理器之类的组件类型来定制灵活的系统/套接字层参数，存储器控制器，IO集线器等。此外，该技术有助于以正确的一组POC值加电，因此避免了多次热复位并提高了启动时间。在一个实施例中，可以消除保存新值的寄存器，例如在复位期间驱动的配置值（CVDR）和在复位期间捕获的配置值（CVCR）。例如，POC值可以来自以下内容：平台输入时钟到核心时钟比率，启用/禁用LT，可配置重新启动，刻录初始化模式，禁用超线程，系统BSP插槽指示和平台拓扑索引。
