Altera emac: Is it TSE or designware?


#1

Hello,

I am a bit confused with altera emac.
I need to use emac from HPS with cyclone V (or arria V ).
Checking both TRM documentation of these FPGA, it is described (in each TRM , and also in memory map ), that it use DesignWare emac.

But I then see in Cyclon V devkit documentation another thing:

“Gigabit Ethernet port
RJ-45 connector which provides a 10/100/1000 Ethernet connection via a Micrel KSZ9021RN PHY and the FPGA-based Altera Triple Speed Ethernet MegaCore function in RGMII mode.”

Is the HPS emac a TSE or DesignWare emac ?

Thank you!
