Class

uvm_tlm_fifo#(T)

This class provides storage of transactions between two independently running processes. Transactions are put into the FIFO via the put_export . transactions are fetched from the FIFO in the order they arrived via the get_peek_export . The put_export and get_peek_export are inherited from the <uvm_tlm_fifo_base #(T)> super class, and the interface methods provided by these exports are defined by the <uvm_tlm_if_base #(T1,T2)> class.

Parameters

Name	Default value	Description
T	int

Variables

Name	Type	Description
type_name	string

Constructors

function new ( string name, uvm_component parent, int size )

The name and parent are the normal uvm_component constructor arguments. The parent should be null if the <uvm_tlm_fifo#(T)> is going to be used in a statically elaborated construct (e.g., a module). The size indicates the maximum size of the FIFO; a value of zero indicates no upper bound.

Functions

virtual function string get_type_name ( )

virtual function int size ( )

Returns the capacity of the FIFO-- that is, the number of entries the FIFO is capable of holding. A return value of 0 indicates the FIFO capacity has no limit.

virtual function int used ( )

Returns the number of entries put into the FIFO.

virtual function bit is_empty ( )

Returns 1 when there are no entries in the FIFO, 0 otherwise.

virtual function bit is_full ( )

Returns 1 when the number of entries in the FIFO is equal to its size, 0 otherwise.

virtual function bit try_get ( int t )

virtual function bit try_peek ( int t )

virtual function bit try_put ( int t )

virtual function bit can_put ( )

virtual function bit can_get ( )

virtual function bit can_peek ( )

virtual function void flush ( )

Removes all entries from the FIFO, after which used returns 0 and is_empty returns 1.

Tasks

virtual function put ( int t )

virtual function get ( int t )

virtual function peek ( int t )
