What is JTAG Debug Level 3 for Nios II?

Hello everyone, I would like to trace program execution on the Nios II. One way - to buy Lauterbach - not interesting. Second way - use SignalTap II and .objdump file - pretty well, but still. And n...

Hi H Danill and Amanda, In the NIOS II GUI you are able to set the debug level as previously but Intel now gives you more flexibility to edit the debug level and utilize the resources. So instead of just selecting the dbug level which will select automatically the required resources now you can set the required resources by yourfelf. Please check the attached page which contains Table 4-7 that has a detailed list of the characteristics of each debug level. Different levels consume different amounts of on-chip resources. As an example you can set the same characteristics of Level 2 as shown in the table with the new GUI as follows: Hardware Breakpoints=2 Data triggers=2 Trace Types= None Trace storage=None On-Chip Trace Frame Size= 128 Please check Table 4-7 here: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/n2cpu_nii5v1.pdf#page=120

Dear Embedded_guy

Thank you for this information, but I guess you don't understand my question.

I got you, by Nios II GUI you mean Platform Designer IP customization, by debug level you mean hardware level.

Now my question is - when I choose with new GUI:

Hardware Breakpoints=0

Data triggers=0

Trace Types= Instruction and Data Trace

Trace storage= On-chip Trace

On-Chip Trace Frame Size= 128

Where can I get this Trace information? What software should I use during the trace?
