WebTo do so, reverse engineering is used to enable fault injection on the IDF designs with minimal changes in the bit-stream. This reduces the time needed to inject a fault significantly thus accelerating the evaluation process. Then this methodology is applied to a case study of a single-chip cryptography application on a ZynQ SoC. Websupport combining NAND Flash devices across chip enables (CE#s) in a relatively straightforward process (see Figure 1). Shorting CE#s together is a common practice when combining NAND Flash blocks. By not shorting CE#s together, as shown in Figure 1, a design retains the flexibility to communicate with only one NAND device at a time.
