What are the features/limitations of a LogiCORE IP Core Hardware Evaluation license?
A LogiCORE IP Core Full System Hardware Evaluation license enables you to run through the entire design flow, including implementation, simulation, and bitstream generation.
However, the generated bitstream contains circuitry that disables the design after two to eight hours of operation at the typical clock rate for the core.
The actual duration of the operational period varies on a core-by-core basis. To start the device working again, you must reload the bitstream (reset or reprogram the device).
