They require external memory to store the configuration data that is sent to them at power up. It is possible for the configuration bitstream to be captured during the transmission and used to configure other FPGAs. This form of intellectual property theft can cause revenue loss to the designer. This reference design provides a solution to prevent FPGA designs from being copied. It allows the FPGA design to remain secure even if the configuration bitstream is captured. This is accomplished by disabling the functionality of the user design within the FPGA until handshaking tokens are passed to the FPGA from the MAX®II device. The MAX II devices are selected for generating the handshaking tokens because they are non-volatile and retain their configuration data during power down.
