Identify two ISP instances

Hi,
I created a In-System Sources and Probes IP and I instantiated two in my design.
Both are from the same module.
I found two ISP instances in In-System Sources and Probes editor that have instance index 0 and 1.
My problem is I can't identify which index number related to which instance in my design.
Can you help me?

Regards,

Masaru

    Can't you tell by the signals you connected to each instance?

    Ýou can also assign names to S&P instances, a four character Instance ID.

      If they generated only one instance of the IP, they would not be able to set different instance IDs for the two copies. In fact, they may show up with the same instance ID in the ISSP file but with different indices selected by the tool.

        Thank you for your reply.
        I have generated IP with Automatic Instance Index Assignment option set.
        When compiling the project, Quartus automatically assigned instance id on all instances.
        But problem is I can't find any information in synthesis report or fitter report file.
        My test project grows big and finally I have four instances in it.
        I could identify the instance from the behaviour of connected signals, you pointed out this method.
        Another workaround, contributor FvM guided me not to use Automatic Instance Index Assignment option.
        I would like to hear from altera person.

    Hi,


    How about not use Automatic Instance Index Assignment option and give four unique instance id.

      Hi Sheng,

      I'm surprised by the very backward responses.
      I think Quartus would be much better if the auto-assignment results were displayed in the report file.

      ShengN,
      Please don't be in hurry.
      The Automatic Instance Index Assignment option is useless for now.
      I would like to request improvement that the report file includes auto-assignment result.
