Problem about SignalTab II

Hi, Can I use the SignalTab II to check the waveform of some output ports or registers when I debug my codes in Nios II IDE 5.1? Thanks.

The NIOS IDE and SignalTapII can use the JTAG at the same time (I know this works on bitblaster, but can't confirm other JTAG hardware.)

*EDIT: I have only verified this for v7.1 and 8.0.

You just need to make sure the processor is stopped in the NIOS IDE before you reprogram the FPGA, or else the programmer complains about JTAG being in use.
