Hi ,

I have a question related to uvm\_tlm\_fifo,  
as seen in port and export communication , the implementation of the port is given by the consumers implementation port and connected via the export , so in case of put method , the producer’s put will call the consumer’s put method, but in the case of tlm\_fifo does the fifo provide the implementation of producer’s put ?  
and if not, the fifo is then connected to the consumer which implements a get port , so how does the consumer get the implementation?

any help in this regard will be of great help!!

Cheers,  
Dheeraj

[See the UVM Cookbook](https://verificationacademy.com/cookbook/analysisport).  
As with any TLM communication in UVM, the uvm\_tlm\_fifo includes a put\_export that connects to the producer’s put\_port. When the producer calls put(), the implementation in the fifo puts the data into the fifo queue.  
On the other side of the uvm\_tlm\_fifo, the consumer can call get() from its get\_port and the get\_export in the fifo implements the function to return the data.

_In reply to [Dhee\_27](https://verificationacademy.com/forums/t/uvm-tlm-fifo/34312/2):_

The uvm\_tlm\_fifo has only an export and it is provding a set of blocking methods (get, put, peek) and nonblocking methods try\_put, try\_get, try\_peek. Additionally there are more methods defined like can\_put …  
By connection a component with a port to the uvm\_tlm\_fifo export per definition the component with the port can execute all the methods provided by the uvm\_tlm\_fifo.
