Ethernet pins for Stratix II with EP2S60F1020C3

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.

Cordially,

Samson Bossé.
