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:
com.xilinx.sysgen.netlist.NetlistInternal: there is no synopsis at
C:/Xilinx/13.3/ISE_DS/ISE/sysgen/scripts/SgMap.pm line 24

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.
