Difference between the uvm_tlm_fifo and uvm_tlm_analysis_fifo

Hi All,

uvm_tlm_analysis_fifo is extended from the uvm_tlm_fifo.
From the source code of the uvm_tlm_analysis_fifo I understood that, this component will support the unbounded size of data. where uvm_tlm_fifo can not support.

Apart from the above difference is there any difference between the uvm_tlm_fifo and the uvm_analysis_tlm_fifo.

Thanks & Regards,

The source code for the class
shows you precisely what the differences are.

The class
supports both bounded and unbounded fifos. But when the constructor of
calls super.new(), it fixes the size argument to unbounded, 0. It also constructs an analysis_export, which implements the necessary write() method, which calls the fifos try_put() method.
