TSE by Using System Console on DE2-115

Hi,

first of all, I am really sorry for the delay of my answer :oops:.

Since two weeks, I tried to use your design as others concerning TSE with NIOS, but I didn't manage to use them in a good way. So I gave up with these reference designs.

I saw that Altera put a new reference design with RGMII (AN647). It seems that this design replaces the one I found on the Wiki. So, I modified it in order to target it for the Cyclone IV on DE2-115 board. I have more success with this new reference design as packets are now sent ... but some of them are only receive and the results are still random for the moment: for example, when configuring sending 10000 packets in the ethernet monitor, the number of received packets is sometimes 12864, sometimes 11796, sometimes another number, sometimes only 1 and then the design is stucked. But this is the same when configuring the link at 10, 100 or 1000Mbps.

So, I guess I have a problem of timing in my design, but I don't see which one for the moment.

This design uses system console and not any Nios for generating and monitoring ethernet packets. You only use Verilog code and TCL scripts for testing all possibilities.

If you have the same DE2-115 board and would like to try this design, it would be nice. Of course, if I manage to use it in a right way, I will let you know.
