UVM Generation

Generate UVM components from Simulink^® subsystems or MATLAB^® functions

Generate Universal Verification Methodology (UVM) test components and a behavioral design under test (DUT) from a Simulink model. You can use the generated components in two ways.

Generate a UVM top model with a testbench and a behavioral (DUT). Use the generated UVM top module as a test environment, and replace the generated behavioral DUT with your own simulation model.
Generate UVM test components, and integrate them into your existing UVM environment.

To use this functionality, download and install the ASIC Testbench for HDL Verifier add-on. This feature also requires Simulink Coder™.

Not all UVM generation functionalities are available in MATLAB Online™.

Featured Examples

Use Templates to Create SystemVerilog DPI and UVM Components

Generate SystemVerilog direct programming interface (DPI) and universal verification methodology (UVM) components from MATLAB® functions using built-in templates. This example also reviews the generated SystemVerilog and how it relates to the template. This example teaches you basic template capabilities, that you can use to create a custom template.

Generate Parameterized UVM Testbench from Simulink

Develop a design and testbench in Simulink® and generate an equivalent simulation for a universal verification methodology (UVM) environment using uvmbuild. You can then extend this testbench to refine your verification using protocol-specific drivers, constrained random sequences, and parameterized scoreboards.

Replace Behavioral DUT with RTL DUT in UVM Testbench

Move from a stand-in C-based design DUT to a simple behavioral RTL DUT interface to a full protocol-based RTL DUT interface that uses AXI4-Lite and AXI4-Stream bus protocols. Several of the UVM components must change, such as the driver and monitor, but you can use reuse the original testbench structure and the sequence and scoreboard components without modification.

Add Random Constraints to Sequences in UVM Testbench

Add constrained random verification to a universal verification methodology (UVM) testbench generated from Simulink®. Both Simulink parameters and input ports to the stimulus generation results in randomizable sequence class data members in the UVM testbench. Through standard UVM class inheritance and factory overrides, the design verification engineer can add new and valuable constrained random test cases to their UVM test suite.

Change Parameters and Coverage Goals of Scoreboard in UVM Testbench

Control the parameters of the response checker in a UVM testbench generated from Simulink®. Such parameterization helps the design verification engineer reuse the scoreboard under different testing scenarios. Simulink parameters to the checker will result in a configuration object whose values can be set in a derived test class (randomized or not) or directly via a command line plusarg.
