Elaboration and Simulation Phases of UVM and OVM

OVM Phases :

The OVM provides the following predefined phases for all ovm_components.

•  build
• connect
• end_of_elaboration
• start_of_simulation
• run
• extract
• check
• report

UVM Phases :

1. new() ------------------------------ The constructor
2. build_phase() --------------------- Create components using new or the factory
3. connect_phase() ----------------- Make port, export and implementation connections
4. end_of_elaboration_phase() ---- After all connections have been hardened
5. start_of_simulation_phase() ---- Just before simulation starts
6. run_phase() ----------------------- Runs simulation
7. extract_phase() ------------------ Post-processing 1
8. check_phase() ------------------- Post-processing 2
9. report_phase() ------------------- Post-processing 3
10. final_phase() --------------------- Backstop
