The ovm_recorder class provides a policy object for recording ovm_objects. The policies determine how recording should be done.
A default recorder instance, ovm_default_recorder, is used when the ovm_object::record is called without specifying a recorder.

| Methods | ||
| record_field | Records an integral field (less than or equal to 4096 bits). | |
| record_field_real | Records an real field. | |
| record_object | Records an object field. | |

integer tr_handle = 0
This is an integral handle to a transaction object. Its use is vendor specific.
A handle of 0 indicates there is no active transaction object.
ovm_radix_enum default_radix = OVM_HEX
This is the default radix setting if record_field is called without a radix.
bit physical = 1
This bit provides a filtering mechanism for fields.
The abstract and physical settings allow an object to distinguish between two different classes of fields.
It is up to you, in the ovm_object::do_record method, to test the setting of this field if you want to use the physical trait as a filter.
bit abstract = 1
This bit provides a filtering mechanism for fields.
The abstract and physical settings allow an object to distinguish between two different classes of fields.
It is up to you, in the ovm_object::do_record method, to test the setting of this field if you want to use the abstract trait as a filter.
bit identifier = 1
This bit is used to specify whether or not an object’s reference should be recorded when the object is recorded.
ovm_recursion_policy_enum policy = OVM_DEFAULT_POLICY
Sets the recursion policy for recording objects.
The default policy is deep (which means to recurse an object).
virtual function void record_field ( string name, ovm_bitstream_t value, int size, ovm_radix_enum radix = OVM_NORADIX )
Records an integral field (less than or equal to 4096 bits). name is the name of the field.
value is the value of the field to record. size is the number of bits of the field which apply. radix is the ovm_radix_enum to use.
virtual function void record_field_real ( string name, real value )
Records an real field. value is the value of the field to record.
virtual function void record_object ( string name, ovm_object value )
Records an object field. name is the name of the recorded field.
This method uses the recursion <policy> to determine whether or not to recurse into the object.
virtual function void record_string ( string name, string value )
Records a string field. name is the name of the recorded field.
virtual function void record_time ( string name, time value )
Records a time value. name is the name to record to the database.
virtual function void record_generic ( string name, string value )
Records the name-value pair, where value has been converted to a string, e.g. via $psprintf(“%<format>”,<some variable>);
The ovm_recorder class provides a policy object for recording ovm_objects.
class ovm_recorder
The ovm_object class is the base class for all OVM data and hierarchical classes.
virtual class ovm_object extends ovm_void
This is an integral handle to a transaction object.
integer tr_handle = 0
This is the default radix setting if record_field is called without a radix.
ovm_radix_enum default_radix = OVM_HEX
Records an integral field (less than or equal to 4096 bits).
virtual function void record_field ( string name, ovm_bitstream_t value, int size, ovm_radix_enum radix = OVM_NORADIX )
This bit provides a filtering mechanism for fields.
bit physical = 1
This bit provides a filtering mechanism for fields.
bit abstract = 1
This bit is used to specify whether or not an object’s reference should be recorded when the object is recorded.
bit identifier = 1
Sets the recursion policy for recording objects.
ovm_recursion_policy_enum policy = OVM_DEFAULT_POLICY
Records an real field.
virtual function void record_field_real ( string name, real value )
Records an object field.
virtual function void record_object ( string name, ovm_object value )
Records a string field.
virtual function void record_string ( string name, string value )
Records a time value.
virtual function void record_time ( string name, time value )
Records the name-value pair, where value has been converted to a string, e.g.
virtual function void record_generic ( string name, string value )
The default recording policy.
ovm_recorder ovm_default_recorder = new()
The record method deep-records this object’s properties according to an optional recorder policy.
function void record ( ovm_recorder recorder = null )
The do_record method is the user-definable hook called by the record method.
virtual function void do_record ( ovm_recorder recorder )
