Description
Automatically detects existing or previously defined communication pathways between GT transmitters and receivers that are defined on the open hardware target.
You can use this command if you change board connections while the serial I/O analyzer is running. The detection algorithm uses changing transmit patterns and detects links on received patterns to determine how GTs are connected to one another on the open hardware target.
A transmitter or receiver of an individual GT on the IBERT debug core can only be used in one hw_sio_link at a time, so the command will not check GTs that are used in existing links. The -force option lets you clear all existing links before scanning the open hardware target to check all GTs.
The detect_hw_sio_links command defines the found links, and creates a link group to associate the new links.
This command returns the number of links found and the created hw_sio_linkgroup object, or returns an error if it fails.
Arguments
-force - (Optional) Delete existing link objects and re-detect links by examining all GTs to ensure the current hardware configuration is properly reflected in the link definitions.
-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.
