Fault Injection
A software reliability testing technique that actively introduces unexpected errors into a system—such as network timeouts or permission denials—to observe system behavior along abnormal execution paths. It is widely used in chaos engineering practices for distributed systems.

According to feedback in the Hacker News comment section, similar hardware-level emulation tools have reference value for homemade hardware, FPGA recreations, and fault-injection research.
Fault injection is widely used in aerospace, automotive, and server chip verification, but usually relies on expensive test platforms.
The C64 hardware-level emulator brings the idea of fault injection to consumer-level scenarios, where researchers can inject pin-level faults in batches and record the system's response.
DialFork's "controlled forking" construction is inspired by the idea of "fault injection" in software testing.
Fault injection testing is a systematic method in reliability engineering that evaluates fault-tolerance capability by deliberately introducing hardware or software anomalies.
Non-invasive methods such as Differential Power Analysis (DPA) and Fault Injection are commonly used to assist in reconstructing the logical behavior of a chip.
