Dear Anand,
First of All thank you for your valuable reply, I have already referred that document. But unfortunately I am configuring RSU IP core in NIOS II software not via RTL design.
Also I want to know that if I disable Watchdog Timer and in case my Application image is corrupted or not available then How system will come back in Factory Image?
Thanks,

Hello,
If the application configuration does not reset the user watchdog timer before time expires, the dedicated circuitry reconfigures the device with the factory configuration and resets the user watchdog timer.
So we need to reset the watchdog timer before time expires.

Hi,
Sorry for the inconvenience caused.
- if Watchdog Time is disable and faulty application it will stalling the device indefinitely. by resting the device to load factory image.
- if Watchdog Time is enable and faulty application or reconfiguration trigger condition, The remote system upgrade circuitry generates a time-out signal. The time-out signal triggers the circuitry to set the user watchdog timer status bit (Wd) in the remote system upgrade status register and reconfigures the device by loading the factory configuration image.
- Look into Register Map of RSU IP for NIOS II software development.

Hello,
Thanks for your support, I have followed the steps you have described above and configured RSU IP core successfully.
One more thing, we have to reset the Watch dog timer after certain interval while system is in application image, so can we have something so that we need not to reset watchdog time to reduce load on application image.
