//Begindoc: Automated Configuration
//This test will focus on testing auto configurations using the ovm_component related config methods.
//
//
//
//To get a more details about the auto config methods of the ovm component, refer to the file:
//	- ovm/src/base/ovm_component.svh , the configuration related part.
//
//
//
//Walk through the test:
//Configuration settings are stored in each component instance. 
//
//Then a search is made to verify that those components full names match the field_name that had been set.
// 
//
//The following configuration interfaces virtual methods will be override:
//
//void set_config_int (string inst_name,string field_name,ovm_bitstream_t value)
//
//void set_config_object (string inst_name,string field_name,ovm_object value, bit clone=1)
//
//void set_config_string (string inst_name,string field_name,string value)
//
