// uvm_root.svh uses these macros to simplify creation of all the phases.
// they are only to be used for UVM builtin phases, because they are simple
// delegate imps that call the corresponding methods on uvm_component.
// Also, they declare classes (uvm_XXXXX_phase) and singleton instances (XXXXX_ph)

// If you require more complex phase functors for your custom phase, code your
// own imp class extending uvm_task/topdown/bottomup_phase base classes, following
// the pattern of the macros below, but customize the exec_task() or exec_func()
// contents to suit your enhanced functionality or derived component type/methods.
// The uvm_user_xxx_phase() macros are provided for your convenience.
