As mentioned in an earlier post, I need an asynchonous instead of a synchronous data memory. The design was working with the BRAM, but
the data was delayed by one cycle. So one would expect when adding
a synchronous memory with the right timing behaviour to get the
design fully working. So I used the core generator 7.1 and generated a dist

You might have good luck buying an inexpensive third-party USB-JTAG cable. However, such cables usually require their own special software, and probably won't work with whatever JTAG software you already have. That could be a disadvantage if your original software has unique features (such as chipscope debugging) that aren't provided in the third-p

There is a perfect way of observing inside the FPGA.
It is chipscope Pro, Xilinx tool and can only be used at Xilinx FPGA.
Great tool for debugging, and can be used as a chip-inside osciloscope.

What problems are you getting? Can you provide the output of chipscope? How about the out of the simulation? You're not giving us a lot to work with here. As your code is, its a pain to read. If you are gonna post it in public, add comments so there can be a general understanding.

I don't think that you enter the first process.
what other devices are connected to the same connection? are you using a router?
Does your PC receive the data when you are using the delay? Have you established the connection between FPGA and PC? Is the header (use Wireshark to check this) correct?
these are just some basic things to check before

you can use textio to output to a file. Or just use the waveform viewer of your favourite simulator.
If you need to check a signal while its running on an FPGA - you'll have to use chipscope (Xilinx) or SignalTap (Altera).

Aside from a bad SDRAM, there might be a timing issue. Did you do a timing simulation or just a functional simulation? Or, your FPGA might be writing to the RAM when you don't intend to. You might also look at your PCB trace lengths, if there is significant differencs in length, and you're running at high speeds, there might be a skew problem.
