  • ISE Simulator (ISim) Error "Simulator is abnormally terminated"

    转自:http://china.xilinx.com/support/answers/33423.htm
    疑问描述


    When I launch a simulation the GUI comes up, but shortly during elaboration of the design, I receive the following error: 

    11.5 and older releases:
    "Simulator is abnormally terminated"

    12.1 and newer releases:

     "The simulator has terminated in an unexpected manner. Please review the ISim log (isim.log) for details."

    The command/terminal console occasionally shows the following error as well:

    "ERROR: FATAL ERROR:ISim: This application has discovered an exceptional condition from which it cannot recover. Process will terminate. To search for possible resolutions to this issue, refer to the Xilinx answer database by going tohttp://www.xilinx.com/support/answers/index.htm and search with keywords 'ISim' and 'FATAL ERROR'. For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support."

    How can I resolve this issue?

    解决方案


    Solution 1

    This error can occur if there were syntax errors or problems while running the simulator executable. For more details, review the ISim log (isim.log) available in the project directory (or working directory, if launching simulation in batch mode). 

    This issue is currently under investigation to better address this condition in a future release of the ISE Simulator.  

    If the information contained in the log file does not help you address the problem, open a WebCase with Xilinx Technical Support for further assistance: http://www.xilinx.com/support/clearexpress/websupport.htm

    Solution 2

    This error can also occur if the simulator engine cannot allocate sufficient memory during elaboration of a large design. This is particularly applicable to Post-Route simulations due to the large structural netlist and timing back-annotation. Additionally, this issue occurs mostly on Windows 32-bit machines as the 32-bit kernel can only allocate 2 GB per process; refer to (Xilinx Answer 14932).

    To resolve this issue: 
    1. Run the simulation on a Linux 32-bit system; as the Linux 32-bit kernel can allocate up to 4 GB of memory. 
    2. Run the simulation on a supported 64-bit system.  For a list of supported 64-bit simulators, refer to http://www.xilinx.com/ise/ossupport/.
    3. Follow the instructions in (Xilinx Answer 14932) to enable 3 GB application support (Windows XP only). 
    This issue is currently under investigation to better address this condition in a future release of the ISE Simulator.
