In-System Programming with Cyclone III

Interesting.. There is no series termination or 0-ohm resistor but I almost wonder if perhaps I botched my soldering job of the EPCS device. I'll also take a look at another test point for the signal, like the pin of the FPGA (pin 23 for DCLK on this one) just to check if there is a more clear signal at the transmission side. I'd think that the reflection will still be apparent at this end since the trace is pretty short, but I'll have a look there anyways.
