Virtualized peripheral component interconnect express (PCIe) device

Abstract:

Examples described herein generally relate to a Peripheral Connect Interconnect Express (PCIe) device. An example is a non-transitory memory storing a representation of a design that is to be implemented on a programmable integrated circuit. The design includes a classifier module (CM), a message trap engine module (MTEM), and a configuration space. The CM is capable of receiving a PCIe message and is configured to determine whether the PCIe message is a PCIe Type 1 configuration transaction. The CM is configured to forward the PCIe message to an endpoint device and to the MTEM when the PCIe message is a non-PCIe Type 1 configuration transaction and the PCIe Type 1 configuration transaction, respectively. The MTEM is configured to virtualize a downstream port(s) of a virtual switch and maintain the configuration space. The MTEM is capable of accessing the configuration space in response to the PCIe message.
