1.1.1. Link Monitor

The link monitor module performs real-time status monitoring of an Ethernet IP link.

It continuously reads and displays all of the required status registers related to the Ethernet IP link. The Link Monitor helps to ensure that all of the Ethernet IP link status at various stages are valid. In case of any failure, it narrows down to the type of failure based on the various status bits, which are based in the register bank of an Ethernet IP core. For more information on the register map, refer to respective Ethernet IP user guide.

Examples of the Ethernet link status displayed on the Link Monitor user interface include:

  • State of Ethernet IP link (Up or Down)
  • State of AN and LT process (Active or Done)
  • Number of correct frames received
  • Number of frame errors
  • Transmitted and recovered clock frequencies etc.

Because the Link Monitor gives out real time link status through Ethernet IP registers, it needs to have a connection with the device that is powered on and configured with the appropriate design file.
