CLASS

uvm_test

This class is the virtual base class for the user-defined tests.

The uvm_test virtual class should be used as the base class for user-defined tests. Doing so provides the ability to select which test to execute using the UVM_TESTNAME command line or argument to the uvm_root::run_test task.

For example

  prompt> SIM_COMMAND +UVM_TESTNAME=test_bus_retry

The global run_test() task should be specified inside an initial block such as

  initial run_test();

Multiple tests, identified by their type name, are compiled in and then selected for execution from the command line without need for recompilation. Random seed selection is also available on the command line.

If +UVM_TESTNAME=test_name is specified, then an object of type 'test_name' is created by factory and phasing begins. Here, it is presumed that the test will instantiate the test environment, or the test environment will have already been instantiated before the call to run_test().

If the specified test_name cannot be created by the uvm_factory, then a fatal error occurs. If run_test() is called without UVM_TESTNAME being specified, then all components constructed before the call to run_test will be cycled through their simulation phases.

Deriving from uvm_test will allow you to distinguish tests from other component types that inherit from uvm_component directly. Such tests will automatically inherit features that may be added to uvm_test in the future.
