In reply to Swetha_ch:
It would help to show an example because parent and child classes are ambiguous terms in UVM. Classes derived from uvm_component (like uvm_test) have parent-child relationships, but many people incorrectly use the same words for inheritance when they really mean base and extened classes.
If you really mean inheritance, virtual methods are used to call extended routines from the base class.
class base_test extends uvm_test;
virtual task run_phase(uvm_phase phase);
...
check_errors();
...
endtask
virtual function void check_errors();
// empty
endfunction
endclass
class extended_test extends base_test;
virtual function void check_errors();
///what you need to check
endfunction
endclass
