How driver and sequencer are connected?

How does a sequencer communicate with the driver? The driver class contains a TLM port called uvm_seq_item_pull_port which is connected to a uvm_seq_item_pull_export in the sequencer in the connect phase of a UVM agent. The driver can use TLM functions to get the next item from the sequencer when required.

What is the use of analysis port in UVM?

WWW.TESTBENCH.IN – UVM Tutorial. The analysis port is used to perform non-blocking broadcasts of transactions. It is by components like monitors/drivers to publish transactions to its subscribers, which are typically scoreboards and response/coverage collectors. For each port, more than one component can be connected.

What are analysis ports?

The idea behind having an analysis port is that a component like monitor should be able to generate a stream of transactions regardless of whether there is a target actually connected to it. When the component (my_monitor) calls analysis_port.

What is the order of steps involved in the communication between sequence and driver?

The handshake between the sequence, sequencer and driver to send the sequence_item is given below. Communication between the Sequence and driver involves below steps, 1….Starting The Sequence:

Method Call	Description
get_response(rsp)	receives the response from driver.

What is an analysis port and analysis FIFO and where are they used?

The ‘port’ is a TLM construct providing a publisher/subscriber mechanism. One publisher – many subscribers and the port is in the publisher. The ‘analysis fifo’ is also a TLM construct having exports and has the ability to store data with the behavior first-in, first-out (FIFO).

What is analysis FIFO?

TLM Analysis FIFO. An analysis_fifo is a uvm_tlm_fifo#(T) with an unbounded size and a write Method. It can be used any place a uvm_analysis_imp is used. Typical usage is as a buffer between a uvm_analysis_port in an initiator component and TLM1 target component.

What is TLM port and analysis port?

Interface Overview

TLM Interfaces, Ports, and Exports
The OVM TLM library defines several abstract, transaction-level interfaces and the ports and exports that facilitate their use.
Analysis	The analysis interface is used to perform non-blocking broadcasts of transactions to connected components.
