Simulation and Verification

[bin2599]

I just purchased ISE 12.2 and I am having problems simulating my design.  I have three FIR filters and one FFT that I developed using Core generator.  I have a top level that instantiate all these modules and I have a test bench to simulate data in to filters and FFT.  when I tried to simulate it I keep getting an error.

"N:/M.63c/rtf/vhdl/src/XilinxcoreLib/fir_compiler_v5_0_sim_pkg.vhd" Line 4649: cannot open file 'inpfile.

What is this mean?  What do I need to do to simulate Xilinx cores such as fir filters and fft.  Is there a simulation file that I have to add as a source file before I run the simulation? 

Thanks,

I was having a similar problem trying to simulate a peripheral in XPS which had a coregen core (an FIR Filter). The inpfile seemed to be the .mif file that coregen generates. I copied the .mif file to the active simulation directory and that seemed to solve the problem for me!
