Using the Xilinx XPS LocalLink Tri-Mode Ethernet MAC
MHS File Syntax
The following code extracts are taken from an XPS project which connected the Ethernet
AVB Endpoint core to an instance of the xps_ll_temac. This design targeted the Virtex-5
family and implemented the xps_ll_temac using an Embedded Tri-Mode Ethernet MAC
macro.
This MHS syntax is included for illustration/guideline purposes. It is recommended that
the XPS GUI is used to import and connect pcore peripherals rather than by manually
editing the .mhs file for a given project. Please refer to Xilinx Platform Studio
documentation.
Certain lines are highlighted and commented to draw attention.
