Vivado 下 IP 核之单端口 RAM 读写

################################################################################ # Vivado (TM) v2020.2 (64-bit) # # README.txt: Please read the sections below to understand the steps required # to simulate the design for a simulator, the directory structure # and the generated exported files. # ################################################################################ 1. Simulate Design To simulate design, cd to the simulator directory and execute the script. For example:- % cd questa % ./top.sh The export simulation flow requires the Xilinx pre-compiled simulation library components for the target simulator. These components are referred using the '-lib_map_path' switch. If this switch is specified, then the export simulation will automatically set this library path in the generated script and update, copy the simulator setup file(s) in the exported directory. If '-lib_map_path' is not specified, then the pre-compiled simulation library information will not be included in the exported scripts and that may cause simulation errors when running this script. Alternatively, you can provide the library information using this switch while executing the generated script. For example:- % ./top.sh -lib_map_path /design/questa/clibs Please refer to the generated script header 'Prerequisite' section for more details. 2. Directory Structure By default, if the -directory switch is not specified, export_simulation will create the following directory structure:- <current_working_directory>/export_sim/<simulator> For example, if the current working directory is /tmp/test, export_simulation will create the following directory path:- /tmp/test/export_sim/questa If -directory switch is specified, export_simulation will create a simulator sub-directory under the specified directory path. For example, 'export_simulation -directory /tmp/test/my_test_area/func_sim' command will create the following directory:- /tmp/test/my_test_area/func_sim/questa By default, if -simulator is not specified, export_simulation will create a simulator sub-directory for each simulator and export the files for each simulator in this sub-directory respectively. IMPORTANT: Please note that the simulation library path must be specified manually in the generated script for the respective simulator. Please refer to the generated script header 'Prerequisite' section for more details. 3. Exported script and files Export simulation will create the driver shell script, setup files and copy the design sources in the output directory path. By default, when the -script_name switch is not specified, export_simulation will create the following script name:- <simulation_top>.sh (Unix) When exporting the files for an IP using the -of_objects switch, export_simulation will create the following script name:- <ip-name>.sh (Unix) Export simulation will create the setup files for the target simulator specified with the -simulator switch. For example, if the target simulator is "ies", export_simulation will create the 'cds.lib', 'hdl.var' and design library diectories and mappings in the 'cds.lib' file.
