This tutorial covers using the Integrated Logic Analyzer (ILA) and Virtual Input/Output (VIO) cores to debug and monitor your VHDL design in the Xilinx Vivado IDE.

In many cases, designers are in need to perform on-chip verification. That is, gaining access to an internal signal’s behavior in their FPGA design for verification purposes.

One option is to bring these signals to the FPGA pins and connect them to LEDs to see their behavior visually.
