UVM Simulation Management

UVM provides a set of classes and methods for controlling the flow of a simulation. This includes starting and stopping the simulation, controlling the execution of sequences, and managing the reporting of results.

UVM Phases

UVM defines a set of standard phases that represent the stages of a simulation. These phases provide a structured way to organize the tasks and activities that need to be performed during a simulation.

Sequencer Arbitration

Multiple sequences can request to send transactions to a sequencer at the same time. UVM provides several arbitration schemes (such as FIFO, RANDOM, and ROUND_ROBIN) to manage and control the order in which these requests are serviced.

Reporting and Message Handling

UVM provides a robust reporting mechanism that allows messages to be categorized by severity and filtered based on verbosity levels. This allows users to control what information is reported and at what level of detail.
