"state_reg/Q"7         Return an array if '-pin' is not present8   -nonbuf: Trace the drivers until none buffer 9@driver: The driver in array format, if '-pin' is not present.10         If the point is floating, @driver is empty, 11         $driver[0]: Driver instance name. It is empty if the driver is port12         $driver[1]: Driver pin or port name. If the driver is a port, it is the port name13         $driver[2]: Driver type. It is string "pin" or "port" depending on the driver is port or leaf cell14         $driver[3]: Driver phase. It is valid when -nonbuf is present, 15                     indicating if the driver path is inverted16                     0: not inverted 1: inverted              17 18<b>Note:</b>191. If '-pin' is present, return a scalar, $driver = get_driver("n12345", "-pin");202. Use 'get_drivers' if there are multiple drivers, the return data has different structure21 22<b>Examples:</b>23 24#1.
