Refresh the PCIe core properties, by reading from HW.


refresh_hw_pcie [‑quiet] [‑verbose] <hw_pcie>


Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
<hw_pcie> Hardware PCIe object




Refresh for the Peripheral Component Interconnect Express (PCIe) debug core object, hw_pcie, defined on the current hardware device.

The customizable LogiCORE IP PCIe core for AMD Versal Adaptive SoCs is designed for evaluating and monitoring the PCIe Link Training and Status State Machine (LTSSM) running on the Gigabit Transceivers (GTs). In the AMD Vivado™ Hardware Manager, Versal PCIe soft cores implemented in the design, are represented as hw_pcie objects. You can use these PCIe debug cores to solve a range of debug and validation problems; from viewing the PCIe link information to the LTSSM state transition diagram.

This command reads data from the PCIe debug core and updates the relevant properties in the hw_pcie object.


-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.
