2.3.1. In-System Sources and Probes

In-System Sources and Probes allow you to read and write to a design by accessing JTAG resources.

You instantiate an Intel® FPGA IP into your HDL code. This Intel® FPGA IP core contains source ports and probe ports that you connect to signals in your design, and abstracts the JTAG interface's transaction details.

In addition, In-System Sources and Probes provide a GUI that displays source and probe ports by instance, and allows you to read from probe ports and drive to source ports. These features make this tool ideal for toggling a set of control signals during the debugging process.
