Hi, 

 

While simulating PCIe IP core using ModelSim with the testbench generated along with the IP core generation,  

LTSSM not entering POLLING.CONFIG state. 

 

The transcript messages are given below. 

# INFO: 1787 ns EP LTSSM State: DETECT.ACTIVE # INFO: 1811 ns EP LTSSM State: DETECT.QUIET # INFO: 5027 ns EP LTSSM State: DETECT.ACTIVE # INFO: 5843 ns EP LTSSM State: POLLING.ACTIVE # INFO: 18707 ns EP LTSSM State: DETECT.QUIET # INFO: 21923 ns EP LTSSM State: DETECT.ACTIVE # INFO: 22739 ns EP LTSSM State: POLLING.ACTIVE # INFO: 35555 ns EP LTSSM State: DETECT.QUIET # INFO: 38771 ns EP LTSSM State: DETECT.ACTIVE # INFO: 39635 ns EP LTSSM State: POLLING.ACTIVE  

 

Expecting your suggestions. 

 

Thank you

Hi Gibin, 

 

Are you also getting any failure messsages like "BFM Model not found"? 

If yes please try to generate the core and simultation files with newer version of Quartus, may be the 

Quartus 12.0 and tru simulating again. I hope your problem will get solved. 

 

Thank you, 

Umesh
