Description
Write the populated hw_sio_sweep object after run_hw_sio_sweep completes.
To analyze the margin of a given link, it is often helpful to run a scan of the link using the specialized features of Xilinx UltraScale devices or 7 series FPGAs. It can also be helpful to run multiple scans on a the link with different configuration settings for the GTs. This can help you determine which settings are best for your design. The Vivado serial I/O analyzer feature enables you to define, run, and save link sweeps, or collections of link scans run across a range of values.
This command saves the specified link sweep object to disk after it has been populated by the run_hw_sio_sweep command.
This command returns the name of the directory created, or returns an error if the command fails.
Arguments
-force - (Optional) Overwrite the specified directory if it already exists.
-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<directory> - (Required) The name of a directory to write multiple scan files as a result of the run_hw_sio_sweep command.
<hw_sio_sweep> - (Required) Specify a hw_sio_sweep object to write to disk. The hw_sio_sweep must be specified as an object as returned by the get_hw_sio_sweeps command.
