signaltap: Can't find the instance

Hi,

I have a problem about using signaltap, when I press Run analysis,there have an Error: Can't find the instance. Download a design with SRAM Object File containing this instance.

What dose this mean?

Thanks!

    But when I download the *.sof file, then capture the data, there have no error.

    Why?

    I guess, it's a different design.*.jic has to be generated manually, unless you have written scripts that make it after compilation.

    Thanks for your reply!

    I download the *.jic file befor run signaltap analysis, then shows the error. Because I want to capture the online data.

    But when I download the *.sof file, then capture the data, there have no error.

    Why?

    It means, that you have to enable the SignalTyp II instance before compiling the design. The error can also indicate, that you haven't downloaded the recent FPGA image.
