#RULESET_NAME#

  • The name of the ruleset, used in generated ruleset documentation.

  • This attribute is optional.

#LIBRARY_NAME#

  • The name of the ruleset library, it can be "uvm" or "ovm".

  • This attribute is optional.

  • If missing it can be set in batch via the "-ovm" flag, or it will default to "uvm".

#INCLUDED_RULESET_FILE#

  • Ruleset files can be included. Only the categories from these rulesets will be included before the categories defined in the current file, the configuration will be skipped.

  • Can be a file. System variables can be used.

#INCLUDED_RULESET_FILE_RELATIVE#

  • Can be "true" or "false".

  • When "true" the path of the included file will be considered relative to the folder containing the ruleset file.

  • When "false" the path of the included file will be considered either absolute or relative to the current working directory.

#INCLUDED_SINCE_DATE#

  • Include in a separate category all new rules added since the specified date.

  • Date format must be: yyyy-MM-dd, for example 2019-01-31

#COMPONENT_TYPE#

  • The type of the component for which a custom base class or name pattern can be defined. It can be one of the following:

    • "ACTIVE_COMPONENT" - default base class: none, default pattern: ".*master.*"

    • "AGENT" - default base class: "xvm_agent", default pattern: ".*_agent"

    • "CONFIGURATION_OBJECT" - default base class: none, default pattern: ".*_cfg|.*_config"

    • "COVERAGE_COLLECTOR" - default base class: none, default pattern: ".*_cov"

    • "DRIVER" - default base class: "xvm_driver", default pattern: ".*_driver|.*_drv"

    • "ENVIRONMENT" - default base class: "xvm_env", default pattern: ".*_env"

    • "MONITOR" - default base class: "xvm_monitor", default pattern: ".*_monitor|.*_mon"

    • "REACTIVE_COMPONENT" - default base class: none, default pattern: ".*slave.*"

    • "SCOREBOARD" - default base class: "xvm_scoreboard", default pattern: ".*_scb"

    • "SEQUENCE" - default base class: "xvm_sequence", default pattern: ".*_seq|.*_vseq"

    • "SEQUENCER" - default base class: "xvm_sequencer", default pattern: ".*_sequencer"

    • "SEQUENCE_ITEM" - default base class: "xvm_sequence_item", default pattern: ".*_item|.*_trans"

    • "TEST" - default base class: "xvm_test", default pattern: none

    • "TESTBENCH" - default base class: none, default pattern: ".*_tb|tb_.*|.*_sve"

  • If a component type is not defined then the architecture model will contain types that match the default values for base class or name pattern according to the defined library name (see above - "xvm" above stands for "ovm" or "uvm" according to the specified library).

  • Patterns are used for rules like "All sequence items must inherit from uvm_sequence_item". In order for this rule not to be a tautology, patterns are used to identify what are sequence item candidates without considering inheritance. Once identified, inheritance is checked.

#COMPONENT_BASE_CLASS#

  • The name of the parent base class used to filter a type of component in the architecture model

  • All the classes that extend this one will be found in the architecture model

#COMPONENT_NAME_PATTERN#

  • If the user defines a name pattern and a base class for a component type, the architecture model will contain types that match at least one of these

  • If the user defines only the name pattern or the base class for a component type then the undefined criteria will be considered the default one according to the component type and the defined library name

#SKIP_FILE_NAME_PATTERN#

  • The name pattern for the files that will be skipped when analyzing the source code

  • The <skip-file> default value depends on the selected library name

#SKIP_ELEMENT_NAME_PATTERN#

  • The name pattern for the elements that will be skipped when creating the architecture model

  • The <skip-element> default value depends on the selected library name

The valid fs-field values are: "last-modified" which will add the last modified date of each file to the failures in that file

    • GIT: This will use git to extract blame information for every failure. This annotation type requires an additional git-field attribute to specify which blame information to extract. The valid git-field values are: "author", "author-mail", "author-time", "committer", "committer-mail", "committer-time", "SHA1" and "summary"

    • P4: This will use Perforce to extract blame information for every failure. This annotation type requires an additional p4-field attribute to specify which blame information to extract. The valid p4-field values are: "author", "revision-number", "date"

    • SVN: This will use svn to extract blame information for every failure. This annotation type requires an additional svn-field attribute to specify which blame information to extract. The valid svn-field values are: "author", "commit", "date"

    • CC: This will use ClearCase to extract blame information for every failure. This annotation type requires an additional cc-field attribute to specify which blame information to extract. The valid cc-field values are: "username", "full-username", "date" and "comment"

    • TAG: This will allow creation of custom tags that can be used inside categories and checks to annotate every failure. This annotation type requires an additional tag-key attribute.
