Problem with the FFT MegaCore

Hi All, 


I am trying to run SignalCompiler block VIA C code (i.e- not manually, VIA my own application).  


When I run it and use "Normal" blocks everything works fine. However, when I run it with the FFT IP core I'm having problems. 


When I try to run SignalCompiler block manually the following situations occur: 


1) When I manually run SignalCompiler without generating the FFT files first (using the IP Testbench)- I see that the HDL files are not generated correctly. The files are created in the same way as when I run the SignalCompiler from my C code.  



2) When I manuuly run SignalCompiler after generating the FFt files- I see that everything is generated correctly. 


This leads me to the conclusion that I don't call the SignalCompiler block in a correct way, when using the FFT IP core (or any other core, for that matter).  


Can anyone here tell me how to call the SignalCompiler block from C code when there is an IP CORE in the design?
