AI Technical Summary

Problems solved by technology

However, there are still relatively few fault injection circuits that implement simulation-based and physical implementations at the same time, and most fault injection circuits are limited to memory banks for fault injection of memory banks, ignoring other data paths in the circuit

[0004] At present, among the relevant information about fault injection that can be consulted, most fault injection circuits rely on specific functions or commands specific to simulation tools, which are extremely poor in portability, and cannot be integrated into physical models for verification, and specific faults The injection method is fixed, and it cannot be customized according to the actual needs of the circuit, and the application area is narrow
