What is meaning of NIOS "Instance ID" in Eclipse ?

I have 3 Nios processors in my design. In QSYS they are named NIOS_1, NIOS_2 and NIOS_3. When I start eclipse to run test code, it offers me a choice of 3 Nios processors to connect to; with names nios2_0, nios2_1 and nios2_2, and instance ID of 0, 1, 2 respectively.

From trial and error, I found that Eclipse nios2_0 connects to my QSYS NIOS_3.

How can I tell which Nios I am connecting to in Eclipse ?

Hi,

You need to add the system ID component. The system ID peripheral safeguards against accidentally downloading software compiled for a different Nios II system. If the system includes the system ID peripheral, the Nios II SBT for Eclipse can prevent you from downloading programs compiled for a different system.

Please check the following page for more info:
