    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： A proposal is discussed that facilitates exchanging parameters for a link layer that allows a variable number of parameters without changing a communication protocol. Likewise, the proposal allows for both components connected via the link to negotiate values for the parameters that are exchanged without a need for external agent intervention or redundancy.

    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.
