Description: On-chip debugging refers to a set of diagnostic and analysis techniques carried out directly on the hardware of the device, such as microcontrollers or FPGAs (Field Programmable Gate Arrays). This methodology allows engineers and developers to identify and resolve issues in the design and operation of integrated circuits more accurately and efficiently. By performing debugging on the chip itself, internal signals and system behavior can be observed in real-time, facilitating the detection of errors that might be difficult to identify through traditional debugging methods. Various architectures, widely used in mobile devices and embedded systems, have integrated debugging features that allow developers to access internal registers and states of the processor. On the other hand, FPGAs offer flexibility in hardware reconfiguration, enabling engineers to implement and test different configurations and debugging algorithms. Together, these techniques not only improve design quality but also reduce development time and costs associated with error correction in later stages of the product lifecycle.
