how to watch the rx_datain , the rx_errdetect ports ?

[Altera_Forum]

Hi  

I am a beginner, and am working on Stratix IV board. How to watch the rx_datain , the rx_errdetect ports ?   I checked Stratix GX device handbook and the forum as well, and there ARE a lot of information about the ports. However, I still do not know how to check or watch the signals(ports).  Should I allocate the signals to some FPGA balls and use a oscilloscope ?  Thanks a lot

- Yes, I often do this and solved lots of problems.

If these signal are not input/output of your top-level entity, I advise you to use SignalTap tool of Quartus, really simple and efficient.

you should be able to signaltap rx_errdetect, however rx_datain is a high-speed serial port and can't be tapped with signaltap (you will get an error or internal error). you should instead tap rx_dataout, which is the deserialized parallel output (think shift register)
