摘要: In one embodiment, a method of detecting corruption of configuration memory is provided. A bitstream of a circuit design that includes at least a first module and a second module is generated. Configuration memory cells used to implement each of the first and second modules are determined. The configuration memory cells are programmed with the bitstream. After programming, configuration memory cells used to implement the first module are checked for corruption at a first frequency, and configuration memory cells used to implement the second module are checked for corruption at a second frequency, with the first frequency being different from the second frequency.
