UVM Transaction-Level Modeling (TLM)

TLM in UVM provides a standardized and efficient mechanism for communication between UVM components. It abstracts the details of signal-level interactions, focusing instead on the data being transferred (i.e., transactions).

TLM Ports

UVM provides several types of TLM ports to facilitate communication between components. These include analysis ports, producer/consumer ports, and initiator/target ports. These ports enable flexible and efficient communication between components.

FIFOs and Sockets

UVM also provides FIFOs and sockets to facilitate TLM communication. FIFOs are used to buffer transactions, while sockets are used as endpoints for communication, allowing transactions to be sent and received.

In the following sections, we'll delve into advanced topics such as constraint random verification and functional coverage, which leverage the features of UVM to create robust and efficient verification environments.
