PCIe AXI Streaming IP Packet Header Slot Number Details

Is the Slot Number information provided in the PCIe header (AXI Streaming IP, Document ID: 790711) the same as the Physical Slot Number of Slot Capabilities Register [31:19] defined in the PCIe Base Specification?

    Hi,


    Both are not define the same thing, Slot Number in the PCIe header and the Physical Slot Number in the Slot Capabilities Register serve different purposes within the PCIe architecture. The former is used for transaction routing and identification, while the latter is used for system management and configuration.

    "The former is used for transaction routing and identification," which can be achieved by Bus and Device numbers or using the Address mapping to BAR. How does this field differ from them? Could you provide more details?

    Hi Wincent,

    Thanks for your response.

    How will the mapping of these end-points based on slot number be done? Is it handled by the main system in the Hierarchy (Root Port) or by the user through user-defined interfaces?
