Quality-of-Results Reporting

You can generate a report on the quality of results (QoR) for the design in its current state by using the create_qor_snapshot command ( or by choosing Timing > Create QoR Snapshot in the GUI).
This command measures and reports the quality of the design in terms of timing, design rules, area, power, congestion, clock tree synthesis,  routing , and so on, It stores the quality information into a set of snapshot files.  You can later retrieve and report the snapshot with the report_qor_snapshot  command. You can also selectively retrieve, sort, and display the desired information from the snapshot with the query_qor_snapshot command. ( or By choosing Timing > Query QoR Snapshot in the GUI).

create_qor_snapshot

create_qor_snapshot
   -name name
   [-power ]
   [-clock_tree ]
   [-show_all ]
   [-route ]
   [-save_mw ]
   [-significant_digits   digits ]
   [-zero_paths  number]
   [-max_paths  number ]
   [-nworst  number]

Alternatively, you can create a QoR snapshot in the GUI by choosing  Timing > Create QoR Snapshot.

The command options let you specify which aspects of quality are to be measured ( power, clock tree, and routes ) and the conditions for analysis ( zero wire load, maximum paths per timing group, and maximum paths per endpoint).

When you use this command, you must at least specify a name for the snapshot by using the -name option.
For Example,
icc_shell> create_qor_snapshot -name my_snapshot1

The report is written to a set of files into a directory called "snapshot" in the current working directory.  Once written, you can retrieve the report any time with the report_qor_snapshot command.

For example,
icc_shell> report_qor_snapshot

query_qor_snapshot
The query_qor_snapshot command reads in a QoR report generated by previous usage of the create_qor_snapshot command and analyzes the results by collecting information about each path. You can query the collected information with various searches and display the results in text
or HTML format, or in an interactive HTML window linked to the GUI layout view. The interactive HTML report lets you quickly find paths with certain problems such as large fanouts or transition degradation, and then view the path in the current design.

This is the syntax of the query_qor_snapshot command:

query_qor_snapshot
   [-name snapshot_name ]
   [-type min | max ]
   [-incremental ]
   [-display ]
   [-output_file file_name ]
   [-output_false_paths  file_name]
   [-sort_by  column_list ]
   [-columns column_list ]
   [-and  column_list ]
   [-filters  filter_list ]
   [-hierarchy ]
   [-from module_list ]
   [-to module_list ]
   [-through  module_list ]
   [-output_group_paths  file_name]
   [-path_group_prefix prefix]

Alternatively, you can create a QoR snapshot in the GUI by choosing Timing > Query QoR Snapshot.

The command options let you filter and sort the query results and display those results in text or HTML format. The command does not perform any addtional analysis of the design, but merely processes the report information
