svt_log_format This class extension is used by the verification environment to modify the VMM log message format and to add expected error and warning capability to the Pass or Fail calculation.
svt_log_callbacks This class is an extension used by the verification environment to catch the pre_abort callback before the simulator exits. In the callback extension, the vmm_env :: report method is called in order to provide context to the events that lead up to the fatal error.
svt_err_check Error Check Class - Tracks error checks performed by a transactor. An object of this class is instantiated in the svt_xactor class (the m_o_err_chk member of that class). Error checks performed by the transactor are registered to this class, and statistic collection objects for them are stored in the checks[$] queue of this class.
svt_err_check_stats Error Check Statistics Class - This class is simply used to encapsulate statistics related to one specific error check. A queue of objects of this class is used within the svt_err_check class (the check member of the svt_xactor class), to track error checks performed by all transactors.
svt_err_check_stats_cov This class defines the covergroup for the svt_err_check_stats instance.

svt_data Base class for all SVT-based model's data object classes (configuration, transaction, etc.).
svt_xml_writer Class which can be used to open and manage the interaction with an XML file for use with the Protocol Analyzer.
svt_pattern Simple data object for describing patterns as name/value pairs along with match characteristics. In addition to the name/value information this includes
  • match_min and match_max
    • Used to define whether the match should repeat
    • Typical matches:
      • If match_min == 1 and match_max == 1 then the match must occur once and only once
      • If match_min == 0 and match == n for some positive n then the match is expected to occur for "up to n" contiguous instances.
  • positive_match (pattern_data)
    • Stored with each name/value pair this indicates whether the individual name/value pair defines a match or mismatch request.
  • positive_match (pattern)
    • Stored with the pattern, indicating whether the overall pattern defines a match or mismatch request.
  • gap_pattern
    • Patterns can sometimes need to describe non-contiguous sequences. In these situations the non-contiguous nature of the match must be described by defining the gaps between the desired match elements. Each gap is itself stored as a pattern, but with the gap_pattern flag set. When set to true the pattern is used to do the match, but is not stored in the match results.
svt_toggle_cov_bit_vector Class used to support toggle coverage for multi-bit buses. Provides this support by bundling together multiple individual svt_toggle_cov_bit instances.
svt_debug_opts The svt_debug_opts class is a singleton class that contains the automated debug options requested by users. Options are provided through the use of runtime plusarg +svt_debug_opts are used to control the behavior of this feature.
svt_debug_opts_carrier The svt_debug_opts_carrier is used to intercept and manage whether the baseline pattern data carrier functionality is actually utilized.
svt_debug_vip_descriptor Data object to save debug information for each SVT VIP in the simulation
svt_vip_writer Utility class used to provide assistance writing information about objects to be displayed with the Protocol Analyzer.
svt_pa_object_data Utility class to hold the object details for Protocol Analyzer or Verdi.
svt_compound_pattern_data Data object for storing an set of name/value pairs.
svt_pattern_data Data object that stores an individual name/value pair.

svt_types This class is a place where enumerated types commonly used by different SVT Classes are collected. The usage model is that any class that wants to use the svt_types provided enumerations must reference the type of interest using a class-scoped type reference. Note that it is not necessary to create an instance of this class. Simply including this class in the compile is sufficient.
