9. Ethernet Toolkit Overview

The Ethernet Toolkit is a TCL based debugging tool that allows you to interact with an Ethernet Intel FPGA IP in real time.
Figure 14. Block Diagram of the Ethernet Toolkit
You can use the Ethernet Toolkit with hardware design that has standalone Ethernet IP. You can also use the Ethernet Toolkit with an Quartus® Prime generated Ethernet IP design example.
