1.5. Simulating the Design Example Testbench
Procedure
Follow these steps to simulate the testbench:
- At the command prompt, change to the testbench simulation directory <design_example_dir>/example_testbench.
cd <my_design>/example_testbench
- Run the simulation script for the supported simulator of your choice. The script compiles and runs the testbench in the simulator. Refer to the following table Commands to Simulate the Testbench in Supported Simulators.
- Analyze the results. The successful simulation displays "Testbench Passed" or "Test Case Passed" message.
Table 8. Commands to Simulate the Testbench in Supported Simulators Simulator Instructions VCS* In the command line, type: sh run_vcs.sh
Note: Dynamic Reconfiguration with AN/LT IP supports only VCS simulators in design example.VCS* MX In the command line, type: sh run_vcsmx.sh
QuestaSim* In the command line, type: vsim -do run_vsim.do
If you prefer to simulate without bringing up the GUI, type:vsim -c -do run_vsim.do
Xcelium* In the command line, type: sh run_xcelium.sh
