Altera Corporation Reference Manual D–1
August 2006 Preliminary
Appendix D. Restoring the
Factory Design
Introduction This appendix provides the following information:
■ “Factory-Programmed Factory Design”
■ “User Designs”
■ “Reprogramming the Factory Design to the EPSC64 Device (U17)”
Factory-Programmed Factory Design
The Cyclone™ II DSP development board is factory programmed with a
factory design stored in flash memory, the EPCS64 (SAFE EPCS) serial
configuration device (U17). When power is applied to the board, the on-
board logic downloads the factory design to configure the EP2C70 FPGA.
User Designs
The EPCS64 serial configuration device (U36) is used to store a user
design. When power is applied to the board, the on-board logic
downloads the user design to configure the EP2C70 FPGA.
Reprogramming the Factory Design to the EPSC64 Device (U17)
During the development process, you may accidentally overwrite the
factory design in the EPCS64 (SAFE EPCS) flash memory serial
configuration device (U17). Altera includes the Programmer Object File
(.pof) factory design in the DSP Development Kit, Cyclone II Edition, so you
can reprogram the Cyclone II DSP development board to the original
factory configuration.
