uvm_tlm_analysis_fifo

[BR]

Having issues using uvm_tlm_analysis_fifo.

Can i do uvm_tlm_analyssis_fifo.try_peek(item)?

TLM analysis FIFO gets item using put from a layer below.

Can someone provide an example to use this properly.

Thanks in advance

The analysis FIFO is an unbounded implementation of TLM FIFOs (tlm_fifo being the base class) does provide different APIs to look into the FIFO, incl. try_peek.

Just to be sure I know what has been done, pl. provide the code snippet of the definition of the TLM interfaces and connection to the FIFO. Also have you created the FIFO in the build phase and the associated TLM interfaces.

For example.

class a extends uvm_scoreboard;

ovm_analysis_export #(item) a_exp;

ovm_tlm_analysis_fifo #(item) a_fifo;

function voild build();

super.build();

a_exp = new ("a_exp", this);

a_fifo = new("a_fifo",this);

endfunction

function void connect();

a_exp.connect(a_fifo.analysis_export);

endfunction

task run();

item l_item;

a_fifo.try_peek(l_item);

endtask

Now the default implementation of the write API function is try_put into the FIFO, which off course has to be implemented on the put side by user defined write API.

Good luck.
