DSP Tools

I've got an ISE 13.3 Planahead project so those are the Xilinx blockset libs that I'm using.

Matlab version is R2011a.

When I run the Resource Estimator (RE) if I design a filter that exceeds the available DSP48 count available in the chip the RE correctly reports that as an error. So far so good.

When I back off the filter parameters to fit nicely into the target FPGA, I get an dialog box to perform mapping (there are blocks in the system with no estimation function).  When I click OK on this I get a java error:

Error using ==> xlCallMapper at 196

Java exception occurred:

This looks like a bug.

I recommend opening a case with the Xilinx Technical Support.

Would you know how to run the resource estimator from the command line?

Ok, opened a webcase, thanks.

Xilinx has indeed confirmed that this is a bug.

The workaround is to set the Project type (System Generator Token) to Project Navigator not PlanAhead. In that case the resource estimator will work just fine.
