Description
This command look for trouble spots in the design and assesses the likelihood of a design meeting design goals. This command requires an open elaborated, synthesized or implemented design for analysis.
- Design Methodology
- Synthesis
- Implementation
- Design Hierarchy
- Partial Reconfiguration
- Floorplanning
The report_qor_assessment command includes a subset of report_methodology checks identifying bad practices that can lead to an expected problem. Yet, report_qor_assessment is also more comprehensive than report_methodology, because it includes other checks that are not necessarily bad practices but may have low success due to the structure, style, size, or complexity of the current design.
A key feature of Report QOR Assessment is the ability to predict certain conditions that lead to congestion and performance degradation. This command can be run at any stage of the implementation flow after synthesis. The report_qor_assessment command will return a score from 1 - 5, where 1 is a failing grade, and 5 means the design will likely pass implementation and meet timing.
For violations found by Report QOR Assessment, the Report QOR Suggestions command will make recommendations on how to avoid issues, or modify the design to improve results.
Arguments
-file <arg> - (Optional) Write the QOR Assessment report into the specified
file. The specified file will be overwritten if one already exists, unless
-append is also specified.-file or
-csv, the file will be written into the current working
directory that can be identified using the [pwd] Tcl
command.-csv_output_dir - Directory to write supporting CSV files. CSV files
contain:- Timing path details and show suggestions that are applicable to the timing path.
- Cells and nets with DONT_TOUCH properties
-append - (Optional) Append the output of the command to the specified file rather than overwriting it.
-append option can only be used with the -file option.
-exclude_methodology_checks - (Optional) By default, methodology
checks are included in the report. This switch prevents methodology checks being
reported and reduces the time taken to execute the command.
-report_all_suggestions - (Optional) When running
report_qor_assessment followed by
report_qor_suggestions, this option should match in both
commands to reduce the compile time.
-max_paths <arg> - (Optional) Specify the number of critical paths to analyze. The default is the 100 worst timing paths.
-full_assessment_details - (Optional) In the Details table, report
items that have passed the checks performed.
-return_string - (Optional) Direct the output to a Tcl string rather than to the standard output. The Tcl string can be captured by a variable definition and parsed or otherwise processed.
name - (Optional) Specifies the name of the results set for the GUI.
-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.
