- # 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.
