3.1.4. Simulating the Design Example Testbench

Procedure
Follow these steps to simulate the testbench:
  1. At the command prompt, change to the testbench simulation directory <design_example_dir>/example_testbench.
  2. Run the simulation script for the supported simulator of your choice. The script compiles and runs the testbench in the simulator. Refer to the table Steps to Simulate the Testbench.
  3. Analyze the results. The successful testbench received five hyperframes, and displays "PASSED".
    Table 19.  Steps to Simulate the Testbench
    Simulator Instructions
    Siemens* EDA ModelSim* SE or QuestaSim* In the command line, type vsim -do run_vsim.do

    If you prefer to simulate without bringing up the ModelSim GUI, type vsim -c -do run_vsim.do

    Note: The Questa* Intel® FPGA Edition simulator does not have the capacity to simulate this IP core. You must use ModelSim* SE or QuestaSim* .
    Synopsys* VCS* / VCS* MX In the command line, type sh run_vcs.sh or sh run_vcsmx.sh
    Xcelium* In the command line, type sh run_xcelium.sh
The following sample output illustrates a successful simulation test run for 24.33024 Gbps with 4 CPRI channels:
