Ethernet MAC/PHY (LAN91C111) with Stratix II

Honored Contributor II

Hello everybody, 


I’m a French student in electronics engineering. 

I’m trying to use the Ethernet MAC/PHY (LAN91C111 device) IP with Nios II but I have some problems with the pins assignments in Quartus II software (v9.0). 

My board is a stratix ii with ep2s60f1020c3 FPGA. 


Can you tell me why I can’t find the System Control Bus pins T20, T21, T25, T26 and V26 indicated in the stratix ii dsp development board reference manual when I use the pin planner of Quartus for ep2s60f1020c3 FPGA? 


Can you tell me what other pins assignments I could make for these pins? 



Thanks in advance.

Ethernet MAC/PHY (LAN91C111 device) is not an IP : is an IC. 

You have to assign signal to pins according to the documentation : page 2-25 of the reference manual. 


Cordially (Cordialement ne se dit pas, on dit Best Regards !) 

Bonne Journée !
