They would both pass their transactions up to the scoreboard and it would decide if the DUT provided the correct output transaction for the given input transaction.

Run-time Phases 3. I need to have a checker module for my SystemVerilog Assertions, but this checker module needs to be aware of register configuration that is done from the test (and can be random, decided during run_phase of the test).

The self-check does the job of first checking if expected_queue.

UVM Base Test Example In the following example, a custom test called base_test that inherits from uvm_test is declared and registered with the factory.

UVM scoreboard is a verification component that contains checkers and verifies the functionality of a design.

The data processing protocol checking is done in data checker which is generally in scoreboard( or tracker).

Testbench environment component called m_top_env and its configuration object is created during the build_phase and setup according to the needs of the test.

We can see in the above UVM Test Run-time Phases i.

by specifying the test name as an argument to run_test (); example: run_test ("mem_model_test"); 2.

Let us see a complete example of how such a model can be written for a given design, how it can be integrated into the environment and how it can be used to write and read into design fields.

UVM Register Model Example In the previous few articles, we have seen what a register model is and how it can be used to access registers in a given design.

Testbench environment component called m_top_env and its configuration object is created during the build_phase and setup according to the needs of the test. .
