Many people do not appreciate what makes a system-on-chip (SoC) different from other semiconductor devices. Many companies, especially in electronic design automation (EDA), toss around the term “SoC” without defining it or explaining why it’s such an important concept.

Multiple sequences can interact concurrently with a driver connected to a single interface. The sequencer supports an arbitration mechanism to ensure that at any point of time only one sequence has access to the driver. The choice of which sequence can send a sequence_item is dependent on a user selectable sequencer arbitration algorithm. 

Callback mechanism is used for altering the behavior of the transactor/BFM without modifying the existing BFM/transactor. Callback gives flexibility to plug-and-play and reuse the components i.e. driver, monitor etc.. 

A semaphore allows you to control access to a resource.Conceptually, a semaphore is a bucket. When a semaphore is allocated, a bucket that contains a fixed number of keys is created.

Fork…Join construct of System Verilog actually enables concurrent execution of each of its statements/threads/processes. This feature is most widely used for forking parallel processes/threads in System Verilog Test Benches. 

The UVM Library has built-in utility and field automation macros that allow objects to be created by the factory and have access to common functions such as copy( ) or clone( ).

Today I am going to talk about virtual sequences and the virtual sequencer. Common questions I hear from users include: why do we need a virtual sequence? How can we use it effectively?

It is necessary to manage most of the verification tasks, such as generating stimulus and collecting coverage data, at the transaction level, which is the natural way of verification engineers tend to think of the activity of a system.

I hope you started understanding assertions and their operators well with practical examples. Let’s start learning more operators in this post.

System Verilog assertions always help to speed up the verification process and it’s very powerful and widely used in the ASIC verification. Identifying the right set of checkers in the verification plan and implementing them using effective SV assertions helps to quickly catch the design bugs and ultimately helps in high-quality design.

As mentioned, an agent is a container that instantiates the driver, monitor, and sequencer. Agents can be either active or passive. In active mode, all three components are created, while in passive mode only the monitor is created. Since we have already built the necessary components, creating the agent is simply a matter of instantiating them.

The job of the sequencer is to control the flow of sequences to the driver. The fact that you can write six lines of code yet have a powerful implementation is the beauty of UVM. Having the sequencer mechanism prepared for you in the library allows you to build the testbench faster and more effectively.
