I implemented image compression based discrete wavelet transform on FPGA, I read the image as mif file from Matlab and implement the image compression on VHDL. However When I use an image size larger than 256 it takes long time to simulate and ends with the following error in isim: ISim P.20131013 (signature 0x8ef4fb42) This is a Full version of ISim. 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 to http://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.ERROR: The simulation failed to launch for the following reason: The Simulation shut down unexpectedly during initialization. Please review the ISim log (isim.log) for details. Please shut down ISim and retry the simulation. If the problem persists, please contact Xilinx support. Time resolution is 1 fs No active Database Unable to execute live simulation command. The simulation has terminated. ISim> I need to simulate an image with size 65536 (256x256). I use Xilinx ISE 14.7 and my OS is Windows 10. Thank you

Hi @farghaly ,

If you are still facing the issue after checking the above mentioned AR then I would suggest you to check the same in Vivado latest version and share the outcome.
