Member Function Documentation

  function svt_pattern
 svt_axi_service::allocate_pattern
 (   ) 

This method allocates a pattern containing svt_pattern_data instances for all of the primitive data fields in the object. The name is set to the corresponding field name, the value is set to 0.

Return values - An svt_pattern instance containing entries for all of the data fields.

 Superseded functions 
 svt_sequence_item_base :: allocate_pattern 

  function bit
 svt_axi_service::decode_prop_val
 (  string prop_name , bit [1023:0] prop_val , ref string prop_val_string , input svt_pattern_data :: type_enum typ  ) 

Simple utility used to convert 'bit [1023:0]' property value representation into its equivalent string property value representation. Extended to support decoding of enum values.

prop_name - The name of the property being encoded.

prop_val_string - The string describing the value to be encoded.

prop_val - The bit vector encoding of prop_val_string.

typ - Optional field type used to help in the encode effort.

Return values - The enum value corresponding to the desc.

 svt_sequence_item :: decode_prop_val 

  function bit
 svt_axi_service::do_compare
 (  ovm_object rhs , ovm_comparer comparer  ) 

Compares the object with rhs..

rhs - Object to be compared against.

comparer - TBD

  function void
 svt_axi_service::do_copy
 (  ovm_object rhs  )

  function bit
 svt_axi_service::do_is_valid
 (  bit silent = 1, int kind = RELEVANT  ) 

Does a basic validation of this status object.

silent - bit indicating whether failures should result in warning messages.

kind - This int indicates the type of is_valid check to attempt.
