SignalTap II or In-System Sources Probes Editor

[Altera_Forum]

Hi, 

I have just upgraded to version 10.1 of QuartusII. I can see a new test interface "In-System Sources Probes Editor". I have always used the SignalTap II for debugging. Can anyone tell me what is better to use for new designs? I have read about the new interface and is it correct that its strength is that it is possible to generate test patterns to input pins?  Regards, Morten

is Sources and Probes really that new of a feature? to me they have slightly different applications. 

 Sources and Probes is great for board bring up to toggle outputs and read inputs without writing any HDL (besides a port map). it is also useful for emulating push buttons or similiar signals  SignalTap is "read only" but has simple and complex triggers. it can buffer a large amount of data which is then read out by JTAG which is really useful for in system debug

For signaltap you don't have to change your source code.  Kind regards  GPK

Thanks for your replies. I think I got a better understanding of the differences between the two.
