Now that you have created a Vivado Design Suite project for the tutorial design, you can set up and launch the Vivado simulator to run post-synthesis functional simulation. Simulation will generate a switching activity values file (SAIF) that will enable you to do more accurate power estimation on your design.
- In the Flow Navigator, click Settings to open the Project Settings dialog box and set the simulation properties in Simulation section.
- In the Simulation
section of Project
Settings dialog box, note that the following Simulation
defaults are automatically set for you based on the design files:
-
Simulator
language:
Mixed -
Simulation
set:
sim_1 -
Simulation
top-module name:
testbench
-
Simulator
language:
- In the Elaboration
tab of Simulation section, make sure the xsim.elaborate.debug_level is set to typical, which is the default value.
- In the Simulation tab enter the SAIF file name as power_tutorial_func.saif for xsim.simulate.saif. Observe that the xsim.simulate.runtime is 1000 ns.
- Click OK.
With the simulation settings properly configured, you can launch the Vivado simulator to perform a post-synthesis functional simulation of the design.
Note: The power reporting and analysis are not performed at the RTL level. They are performed at the gate level. - In the Flow Navigator, click .
When you launch the Run Post-Synthesis Functional Simulation command, the Vivado simulator is invoked to run the simulation.
After the simulation completes, click x at the top right corner to close the simulation window.
