In this step, you launch the AMD Vivado™ simulator GUI by running the xsim command with the simulation snapshot that you generated using the xelab command in Step 2: Building the Simulation Snapshot. After you complete this step, you can use the Vivado simulator GUI to explore the design in more detail.

In the same command window that you used for Step 2, type the following command:

xsim run_sineGen -gui -wdb simulate_xsim.wdb -view xsim_waveConfig


  • run_sineGen -gui: Specifies the simulation snapshot that you generated using xelab, and launches Vivado simulator in GUI mode.
  • -wdb: Specifies the file name of the simulation waveform database file to output, or write, upon completion of the simulation run.
  • -view: Opens the specified waveform configuration file within the Vivado simulator GUI.
Note: You can use the waveform configuration file specified above, or use the tutorial_1.wcfg file that you created in Lab 2 of this tutorial.
The Vivado Simulator GUI opens and loads the design (see the following figure). The simulator time remains at 0 ns until you specify a run time. Run the simulation and explore the design by typing : run -all.
