Overview
--------
ELFWS was created after going through warning triage for an FPGA design.
The synthesis tool provided the ability to suppress warnings, but only at the warning id level.
The place and route tool did not supply any ability to suppress warnings.
Eventually a design change induced a new warning.
Unfortunately, it was not detected until much later in the design process.
A design change was required to resolve the warning.
The change was minor, but could have resulted in major design changes if it could not have been resolved.
Key Benefits
------------
* Standardizes warning suppression definition
* Provides warning suppression for tools that do not support suppressions
Key Features
------------
* Warning definition
* Uses YAML to define suppression rules
* Can include justifications for warning suppression
* Continuous Integration tool support
* command line tool
* outputs JUnit XML files
* Audit Reports
* which rules suppressed which warnings
* rules which did not suppress any warnings
* warnings which were suppressed by multiple rules
Installation
------------
You can get the latest released version of ELFWS via **pip**.
.. code-block:: bash
pip install elfws
The latest development version can be cloned...
.. code-block:: bash
git clone https://github.com/jeremiah-c-leary/eda-log-file-warning-supressor.git
...and then installed locally...
.. code-block:: bash
python setup.py install
Usage
-----
ELFWS can be invoked using **elfws** at the command line prompt:
.. code-block:: bash
$ elfws
usage: elfws [-h] {create,report,show,suppress,version} ...
Suppresses Warnings in logfiles.
positional arguments:
{create,report,show,suppress,version}
create Create suppression file
report Generate an audit report
show Show warnings in logfiles
suppress Suppresses warnings in logfiles
version Displays ELFWS version information
optional arguments:
-h, --help show this help message and exit
ELFWS has five subcommands: create, report, show, suppress and version.
create
------
Use the create subcommand to generate a suppression rule file from a given warning file.
This can be used as a starting point for a suppression file.
Care should be taken as the output messages are not formatted to support regular expressions.
The arguments for the subcommand can be listed using the *-h* option:
.. code-block:: bash
$ elfws create -h
usage: elfws create [-h] [--suppression_file SUPPRESSION_FILE]
log_file output_suppression_file
positional arguments:
log_file Log file with warnings to extract
output_suppression_file
Suppression file to create
optional arguments:
-h, --help show this help message and exit
--suppression_file SUPPRESSION_FILE
Existing suppression file to filter out existing
report
------
Use the report subcommand to generate detailed output of suppression warnings.
The report will show the following information:
* Unsuppressed warnings
* Which suppression rules suppressed which warnings
* Unused suppression rules
* Warnings that were suppressed by multiple suppression rules
* Summary of suppression rules and warnings
The report can be used during reviews to ensure the suppressions are valid.
This command has the option argument **--junit**, which will output a JUnit XML file.
This file can be used with continuous integration tools to check for new warnings.
The arguments for the subcommand can be listed using the *-h* option:
.. code-block:: bash
$ elfws report -h
usage: elfws report [-h] [--junit JUNIT] log_file suppression_file report_file
positional arguments:
log_file Log file to check for warnings
suppression_file YAML formatted warning suppression file
report_file Output report file
optional arguments:
-h, --help show this help message and exit
--junit JUNIT Generate JUnit XML file JUNIT
show
----
Use the show subcommand to list all the warnings in a logfile.
This can be useful when first starting out suppressing warnings and a suppression rule file does not exist.
The arguments for the subcommand can be listed using the *-h* option:
.. code-block:: bash
$ elfws show -h
usage: elfws show [-h] log_file
positional arguments:
log_file Log file to show warnings
optional arguments:
-h, --help show this help message and exit
suppress
--------
Use the suppress subcommand to suppress warnings in a logfile.
This can be useful when creating a suppression rule file.
It reports the results to the screen and only shows warnings which have not been suppressed.
This subcommand can also be used to support a continuous integration (CI) flow using the *--junit* option.
The *--junit* option will create a JUnit XML file which can be read by CI tools.
The arguments for the subcommand can be listed using the *-h* option:
.. code-block:: bash
$ elfws suppress -h
usage: elfws suppress [-h] log_file suppression_file
positional arguments:
log_file Log file to check for warnings
suppression_file YAML formatted warning suppression file
optional arguments:
-h, --help show this help message and exit
version
-------
Use the version subcommand to report the installed version of ELFWS.
There are no arguments for this subcommand.
.. code-block:: bash
$ elfws version
EDA Log File Warning Suppressor (ELFWS) version 1.0.0
