    摘要: A method and apparatus is provided wherein a central Credit Controller Entity (CCE) is connected to a PCIE fabric environment by means of several buses. Flow Control information sent to the CCE over two of the buses indicates the buffer storage capacity that is available at respective Receiver components in the PCIE fabric. The CCE processes the Flow Control information, to generate updates that are sent by a third bus to Transmitter components corresponding to the Receivers. In one useful embodiment, directed to a method of Flow Control management, the CCE provides a repository adapted to store credit count information that represents the available storage capacity of respective Receivers. The method further comprises routing further credit count information from a given Receiver to the CCE, for storage in the repository, following each of successive events that affect the storage capacity of the given Receiver. The CCE is operated to selectively process the credit count information stored in the repository, in order to generate an update credit count. The update credit count is then selectively sent to a given Transmitter, to enable the given Transmitter to send a transmission to the given Receiver.

    摘要: A method for verifying a protocol employed by a protocol handler. In an embodiment, the method includes verifying a Receive Link Layer defined within a protocol handler with Open Vera Assertions. The Receive Link Layer may include a plurality of interfaces and is configured for separating data into a series of packets. Further, a plurality of features included within the series of packets are monitored with Open Vera Assertions. Additionally, functional coverage is measured with coverage statements based upon Open Vera Assertions. Finally, Open Vera Assertion severity and error isolation is controlled through message logging.
