4.1. About the Intel® Quartus® Prime Logic Analyzer Interface
The LAI connects a large set of internal device signals to a small number of output pins. You can connect these output pins to an external logic analyzer for debugging purposes. In the Intel® Quartus® Prime LAI, the internal signals are grouped together, distributed to a user-configurable multiplexer, and then output to available I/O pins on your Intel-supported device. Instead of having a one-to-one relationship between internal signals and output pins, the Intel® Quartus® Prime LAI enables you to map many internal signals to a smaller number of output pins. The exact number of internal signals that you can map to an output pin varies based on the multiplexer settings in the Intel® Quartus® Prime LAI.
The LAI does not support Hard Processor System (HPS) I/Os.
