Ethernet MAC/PHY (LAN91C111) with Stratix II

[Altera_Forum]

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.

Don't trust Altera's documentation for the pins assignments, it seems to be wrong (it's not the first time, unfortunately). 

Have a look at the schematics to find the correct pins instead. From what I'm seeing (I hope I found the correct schematic on the net), those are the correct assignments: [list][*]ENET_DATACS_N: AB24 instead of T20 [*]ENET_IOCHRDY: AB25 instead of V26 [*]ENET_LDEV_N: AA24 instead of T26 [*]ENET_SRDY_N: AA23 instead of T25 [*]ENET_W_R_N: AE27 instead of T21[/list] You should check all the other pins too, you never know what other mistakes they made in their documentation...

Have a look at this page (http://www.altera.com/products/devkits/altera/kit-dsp-2s60.html). If it is indeed your board on the picture, you'll find the schematics in the table 2 at the bottom of the page.
