- Description:
The
l1 resultsfunction provides information about ports specified for the L1 configuration. JSON package is required to use l1_results function as it internally returns values in JSON format.This function returns the requested data and a status value (1 for success). If there is an error, the function returns the status value (0) and an error message. Function return values are converted from JSON format to a keyed list (supported by the Tcl extension software - TclX). Use the TclX function keylget to retrieve data from the keyed list.
Examples:
To retrieve L1 port statistics from the specified port:
l1 results port_handle= port1 result_type= l1_port_statsSample Output:
{port1 {{l1_port_stats {{0 {{link_status ERROR} {rx_ppm_offset -763} {fpga_temp 48.98408095703121} {module_temp null} {module_volt null}}}}}}} {status 1}To retrieve L1 port statistics from the specified port, also stop and delete the test at the end of execution:
l1 results port_handle= port1 lane_num_list= "0 1 2" result_type= "l1_prbs_pam4_stats" clear_db= 1Sample Output:
{port1 {{l1_prbs_pam4_stats {{0 {{l1_prbs_pam4_lane_num 0} {prbs_detected false} {rx_pattern PRBS} {bitswap NONE} {bit_errors 0} {sync_sec 0} {unsync_sec 0}}} {1 {{l1_prbs_pam4_lane_num 1} {prbs_detected false} {rx_pattern NONE} {bitswap NONE} {bit_errors 0} {sync_sec 0} {unsync_sec 0}}} {2 {{l1_prbs_pam4_lane_num 2} {prbs_detected false} {rx_pattern NONE} {bitswap NONE} {bit_errors 0} {sync_sec 0} {unsync_sec 0}}}}}}} {status 1}End of Procedure Header
