proc_qor
Sourcing the attached proc_qor.tcl gives access to the following two procedures to generate and compare more readable QoR files than those produced by the report_qor command:
proc_qor
Reformats the output of the report_qor command.
proc_compare_qor
Compares up to six report_qor or proc_qor output files.
These procedures can be used in IC Compiler, Design Compiler, and PrimeTime with or without multicorner-multimode (MCMM) and generate CSV files for importing to Microsoft Excel.
Usage of proc_qor
proc_qor [-existing_qor_file report_qor file] [-csv_file output_csv_file_name] [-units ps or ns] [-skew]
-existing_qor_file report_qor file
Specifies the name of an existing report_qor report file to reformat.
If you do not specify this option, proc_qor runs the report_qor command on the currently opened design to generate a QoR report file.
-csv_file output_csv_file_name
Specifies the name for the output CSV file.
If you do not specify this option, proc_qor creates a file named qor.csv.
-skew
Adds skew columns for the worst negative slack and total negative slack paths accounting for clock reconvergence pessimism removal. Examples of proc_qor
The following example runs the report_qor command and reformats the generated report. The reformatted report is also shown. Note that the path group names in the generated report have been changed deliberately.

Usage of proc_compare_qor
proc_compare_qor [-csv_file output_csv_file_name] [-tag_list "column_headings"] -qor_file_list "report_files"
-csv_file output_csv_file_name
Specifies the name for for the output CSV file.
If you do not specify this option, proc_compare_qor creates a file named compare_qor.csv.
-tag_list “column_headings”
Specifies the column headings used for the report files. The number of strings specified must equal the number of report files specified.
If you do not specify this option, proc_compare_qor uses qor_i for the column headings, where i is 0 for the first report file and is incremented by one for each report file.
-qor_file_list “report_files”
Specifies the names of the QoR report files to compare. You can specify up to six report files. The report files can be
- Report files generated by the report_qor command
- Report files generated by proc_qor with or without the -skew option
- A combination of these report files
Examples of proc_compare_qor
The following command compares the rp1.qor and rp2.qor reports. The generated report uses the default column headings of “qor_0” and “qor_1”.
icc_shell> proc_compare_qor -qor_file_list “rp1.qor rp2.qor”
qor_0 qor_1 qor_0 qor_1 qor_0 qor_1 qor_0 qor_1 qor_0 qor_1 qor_0 qor_1

The following command compares the rp1.qor and rp2.qor reports and pipes the result to a file named compare.qor. The column headings are “place” and “clock” instead of “qor_0” and “qor_1”.
icc_shell> proc_compare_qor -qor_file_list “rp1.qor rp2.qor” [-tag_list “place clock”] > compare.qor
The following example compares five report files and uses column headings of “dc”, “place”, “clock”, “route”, and “pt” in the generated report.
icc_shell> proc_compare_qor \ -qor_file_list "dc.qor place.qor clock.qor route.qor pt.qor" \ -tag_list "dc place clock route pt"
LIMITATIONS
The clock reconvergence pessimism removal (CRPR) value used when you specify the -skew option with proc_qor might not match the report_timing output, but it is close. See the UITE-468 message. The calculated frequency (FREQ) is based on the worst negative slack (WNS) and clock period reported in the report_qor output and is not accurate in some cases, such as pure combinational paths, half paths, or multicycle paths. In PrimeTime, due to runtime and complexity, only 25 thousand paths per path group and simple methods are used to calculate total negative slack (TNS) and number of violating paths (NVP). proc_qor.tcl - contains both proc_qor and proc_compare_qor procedures
