hi,everyone.I am verifying Gigabit Ethernet. Since my board does not have a PHY , I want to configure the mac to self-loopback mode.I configured the ip core according to the manual, but the simulation failed after the synthesize.The configuration method is as follows.
Can someone tell me how to configure，Or recommend me a suggestion that I can loop back without going through phy.
Thank you again.
Hi, The Loop_ENA bit is used to enable the MAC Loopback, and it should work. You can refer to the TSE user guide, section Section 5.3, when you set the TX_ENA & RX_ENA, you can also set the Loop_ENA to 1.
As for the example design, you can refer to the AN647, there is a tcl script that allow the use to configure the internal MAC loopback (page 17).
