6.2.3. Signal Tap Logic Analyzer

The Signal Tap logic analyzer, available in the Quartus® Prime software, captures and displays the real-time signal behaviour in an Intel FPGA design. Use the Signal Tap logic analyzer to probe and debug the behaviour of internal signals during normal device operation, without requiring extra I/O pins or external lab equipment.

The Signal Tap logic analyzer can aid the Nios® V processor debugging by catching software-related problems, such as an interrupt service routine that does not clear the interrupt signal properly.
