2.17. Generating Simulation Files for Platform Designer Systems and IP Variants
To generate the simulation model and simulator setup scripts for your Platform Designer system or component, follow these steps:
- Click Tools > Platform Designer. Platform Designer and open or create a Platform Designer system or IP variant.
- In Platform Designer, after specifying parameters, click Generate > Generate HDL. The Generation dialog box appears.
- Under Simulation, specify Verilog or VHDL for the Create simulation model option.
Figure 52. Simulation Options in Generation Dialog Box
- Turn on or off the ModelSim, VCS-MX, VCS, Riviera-Pro, or Xcelium option to generate simulator setup scripts for the simulation tool. If you turn on no simulator options, the scripts generate for all simulators.
- Click the Generate button. Platform Designer generates the simulation models and setup scripts for your system or IP component in the following directory:
<top-level system name>/<system name>/<sim>/<simulator>
Figure 53. Generated Simulation Files Location
By default, Platform Designer generates the simulation scripts for the currently loaded system and all subsystems. Alternatively, you can open a subsystem to generate a simulation script only for that subsystem.
You can use scripts to compile the required device libraries and system design files in the correct order and elaborate or load the top-level system for simulation.
Variable | Description |
---|---|
TOP_LEVEL_NAME | If the testbench Platform Designer system is not the top‑level instance in your simulation environment because you instantiate the Platform Designer testbench within your own top-level simulation file, set the TOP_LEVEL_NAME variable to the top-level hierarchy name. |
QSYS_SIMDIR | If the simulation files generated by Platform Designer are not in the simulation working directory, use the QSYS_SIMDIR variable to specify the directory location of the Platform Designer simulation files. |
QUARTUS_INSTALL_DIR | Points to the Quartus installation directory that contains the device family library. |
Top-Level Simulation HDL File for a Testbench System
The example below shows the pattern_generator_tb generated for a Platform Designer system called pattern_generator. The top.sv file defines the top-level module that instantiates the pattern_generator_tb simulation model, as well as a custom SystemVerilog test program with BFM transactions, called test_program.
module top();
pattern_generator_tb tb();
test_program pgm();
endmodule
