Circuit analysis is used to find out how a device works, what components it includes, and how these components interact.
Special attention is paid to printed circuit boards (PCBs). Circuit analysis of printed circuit boards involves the recognition of key elements and the construction of a diagram of their interaction. Among the key elements are microcircuits, RAM modules, ROMs, signal converters etc.
Circuit analysis is the basis for the construction of a functional diagram of a printed circuit board or the entire device.
It also includes searching for debug interfaces on the board. Connecting to suchlike interfaces providesbetter understanding of the working principle of the device.
It also helps to analyze the component interaction on a printed circuit board (PCB). In the case of using standard or proprietary protocols, the data transmitted between the components of the board can be analyzed and decrypted.
