I have created FFT core and now want to simulate it, I am trying it using the verilog text fixture. when I run Simulate Behavioral Model, ModelSim opens but does not simulate it, rather it gives error. Can any one help what the problem is??

From Windows program menu, go to Xilinx ISE Design Suite 11->ISE->Accessories->Simulation Library Compilation Wizard, then follow the instructions from the wizard. It will generate a modelsim.ini file in the ISE installation directory (%XILINX%/ise). I usually copy it and overwrite the one in Modelsim installation directory.

 

Cheers,

Jim

It gives the error "ERROR LOADING DESIGN" in ModelSim,

 

Instantiation of 'SRL16E' failed. The design unit was not found.

Instantiation of 'LUT4' failed. The design unit was not found.

Instantiation of 'MUXF5' failed. The design unit was not found.

Instantiation of 'FDRE' failed. The design unit was not found.

 

Any many similar instantiation errors, Please help to get it solved

Did you compile the ISE simulation libraries (you can use "Simulation Library Compilation Wizard")? If yes, can you check if your modelsim.ini file has correct mappings to the compiled libraries?
