8.7.1. Steps to Simulate the Design Example

  1. Navigate to <design-example-directory>/example_design/testbench.
  2. Type the appropriate command for your simulator:
    Simulator Command
    VCS* sh run_vcs.sh
    VCS* MX sh run_vcsmx.sh
    QuestaSIM* -c -do run_vsim.tcl
    Xcelium* sh run_xcelium.sh
  3. Observe the simulation output. A successful simulation displays a TEST PASSED message.

    The following sample output illustrates a successful simulation test run for the Symmetric Cryptographic Accelerator Hard IP design example testbench:
