What device is commonly used to trace a logic path?

The device commonly used to trace a logic path is a logic analyzer. A logic analyzer is specifically designed to capture and display multiple signals from a digital circuit, allowing technicians to observe the interactions and timing of different logic states over time. This capability makes it invaluable for debugging complex digital systems, as it can show how signals propagate through a circuit, helping to identify issues in logic paths.

A logic pulser is typically used to send pulses through a circuit to test functionality, which provides information about whether a section of the circuit is responsive but does not specifically trace the logic path. A logic gate is a fundamental building block used in digital circuits for various logic operations, and while it forms part of the logic path, it does not provide the capability to trace or analyze the path itself. A microcontroller acts as a small computer on a chip that can be programmed for numerous applications, but it is not designed for tracing logic paths directly.

The reason the logic analyzer is the most suitable choice is due to its ability to provide a visual representation of the signals and their timing, enabling thorough analysis of how data is processed through various logic gates and components in a circuit.
