In AMD Vitis™ tools, there have traditionally been two options for functional simulation of subsystems. The first is Vitis Model Composer, which enables simulation of subsystems comprising of AIE engines and programmable logic (PL) within the Simulink graphical environment. The second is a command-line interface (CLI) approach, which involves manually providing data files for each simulation run to model the subsystem.
Vitis Functional Simulation (VFS) introduces an alternative by supporting simulation management of the design under test (DUT) in MATLAB , Python, and C++ style high-level, text-based environments.
Starting with 2026.1 tool release, Vitis Functional Simulation is documented in its own user guide UG1864 Vitis Functional Simulation User Guide.
Vitis tutorials contain several examples that use Vitis Functional Simulation, here are some of them:
