Until this point, clocks are treated as ideal networks. CTS builds a physical buffer tree to distribute the clock signal evenly to all sequential elements.
Create power and ground networks. Common commands include derive_pg_connection for logical connections and create_rectangular_rings / create_power_straps for the physical mesh. # Set placement options set_app_options -name place_opt
