Reconfigure entire FPGA without using external pin

Good morning,

Thanks a lot for your tips. On other FPGA-Boards we also use some reset-circuits. But because on the actual board the FPGA is master of the whole system the idea is to reset the device from internal logic without the use of external components. Perhaps i'm able to get the remote-update-core working properly, which seems to include the monostable-functionality you described. If there is no way to do this we would have to re-design our board and use some external circuits.
