These scripts are valid only for running simulations for "Open IP Example Design" 1. How to run simulations in Modelsim/QuestaSim simulator A) sim.do File : a) The 'sim.do' file has commands to compile and simulate memory interface design and run the simulation for specified period of time. b) It has the syntax to Map the required libraries (unisims_ver, unisim and secureip). The libraries should be mapped using the following command vmap unisims_ver <unisims_ver lib path> vmap unisim <unisim lib path> vmap secureip <secureip lib path> Also, $XILINX_VIVADO environment variable must be set in order to compile glbl.v file c) Displays the waveforms that are listed with "add wave" command. B) Steps to run the Modelsim/QuestaSim simulation: a) The user should invoke the Modelsim/QuestaSim simulator GUI. b) Change the present working directory path to the sim folder. In Transcript window, at Modelsim/QuestaSim prompt, type the following command to change directory path. cd <sim directory path> c) Run the simulation using sim.do file. At Modelsim/QuestaSim prompt, type the following command: do sim.do d) To exit simulation, type the following command at Modelsim/QuestaSim prompt: quit -f e) Verify the transcript file for the memory transactions. 2. How to run simulations in Vivado simulator A) Following files are provided : a) The 'xsim_run.bat' is the executable file for Vivado simulator under MicroSoft Windows environment. b) The 'xsim_run.sh' is the executable file for Vivado simulator under Linux environment. c) The 'xsim_run.bat'/'xsim_run.sh' file has commands to compile and simulate memory interface design and run the simulation for specified period of time. d) xsim_options.tcl file has commands to add waveforms and simulation period. e) xsim_files.prj file has list of rtl files for simulating the design. f) $XILINX_VIVADO environment variable must be set in order to compile glbl.v file B) Steps to run the Vivado Simulator simulation: a) Change the present working directory path to the sim folder of "Open IP Example Design" path in the OS terminal. b) Run the simulation using xsim_run.sh file under Linux environment and xsim_run.bat under MicroSoft Windows environment. c) Verify the transcript file for the memory transactions. 3. How to run Cadence IES Simulations A) ies_run.sh File : a) The "ies_run.sh" file contains the commands for simulation of the hdl files. b) Libraries must be mapped before running simulations. Following procedure must be followed to before running simulations 1. Create two files named cds.lib and hdl.var in this directory 2. Create a directory 'worklib' in same directory. mkdir worklib 3. Add following lines in the cds.lib file to map Xilinx libraries DEFINE unisim /proj/xbuilds/2014.4_daily_latest/clibs/ius/13.20.005/lin64/lib/./unisim DEFINE unisims_ver /proj/xbuilds/2014.4_daily_latest/clibs/ius/13.20.005/lin64/lib/./unisims_ver DEFINE secureip /proj/xbuilds/2014.4_daily_latest/clibs/ius/13.20.005/lin64/lib/./secureip DEFINE worklib ./worklib 4. ATTENTION: In above lines replace the path for libraries as per your compiled Xilinx libraries directory 5. ATTENTION: Add the lines in the same order given above 6. Please make sure you need to map all Xilinx libraries mentioned above 7. Save and close the cds.lib file Also, $XILINX_VIVADO environment variable must be set in order to compile glbl.v file and the above mentioned library files B) Steps to run the IES simulation: a) Change the present working directory path to the sim folder of "Open IP Example Design" path in the OS terminal. b) Run the simulation using ies_run.sh file. Type the following command: ./ies_run.sh c) Verify the ies_sim.log file for the memory transactions. 4. How to run Synopsys VCS Simulations A) vcs_run.sh Fi
