TSE newbie starter questions

Well ... your explanation isn't exactly clear. You say you added the TSE MAC and it's necessary components to your SOPC system. There are example designs in the example folder of your NIOS II EDS install. In short, you will need:

1 - The TSE MAC

2 - Two SGDMA controllers (one for transmit and one for receive)

3 - Onchip memory (to store the descriptors for the SGDMA controllers)

Once you've added all those to your system and connected them appropriately, you'll need to build your SOPC system. Then you'll have to edit your top level project file (Verilog, or schematic maybe?) and connect all of the port from the TSE MAC to the appropriate pins on the FPGA.

I'm assuming your Stratix II GX board has a PHY on it correct?
