CLASS

uvm_tlm_fifo_base #(T)

This class is the base for <uvm_tlm_fifo#(T)>. It defines the TLM exports through which all transaction-based FIFO operations occur. It also defines default implementations for each interface method provided by these exports.

The interface methods provided by the put_export and the get_peek_export are defined and described by <uvm_tlm_if_base #(T1,T2)>. See the TLM Overview section for a general discussion of TLM interface definition and usage.

Parameter type

T

The type of transactions to be stored by this FIFO.

Parameters

Name	Default value	Description
T	int

Variables

Name	Type	Description
put_export	uvm_put_imp#(int, uvm_tlm_fifo_base#(int))	The put_export provides both the blocking and non-blocking put interface methods to any attached port: task put (input T t) function bit can_put () function bit try_put (input T t) Any put port variant can connect and send transactions to the FIFO via this export, provided the transaction types match. See <uvm_tlm_if_base #(T1,T2)> for more information on each of the above interface methods.
get_peek_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))	The get_peek_export provides all the blocking and non-blocking get and peek interface methods: task get (output T t) function bit can_get () function bit try_get (output T t) task peek (output T t) function bit can_peek () function bit try_peek (output T t) Any get or peek port variant can connect to and retrieve transactions from the FIFO via this export, provided the transaction types match. See <uvm_tlm_if_base #(T1,T2)> for more information on each of the above interface methods.
put_ap	uvm_analysis_port#(int)	Transactions passed via put or try_put (via any port connected to the put_export) are sent out this port via its write method. function void write (T t) All connected analysis exports and imps will receive put transactions. See <uvm_tlm_if_base #(T1,T2)> for more information on the write interface method.
get_ap	uvm_analysis_port#(int)	Transactions passed via get , try_get , peek , or try_peek (via any port connected to the get_peek_export) are sent out this port via its write method. function void write (T t) All connected analysis exports and imps will receive get transactions. See <uvm_tlm_if_base #(T1,T2)> for more information on the write method.
blocking_put_export	uvm_put_imp#(int, uvm_tlm_fifo_base#(int))	The following are aliases to the above put_export.
nonblocking_put_export	uvm_put_imp#(int, uvm_tlm_fifo_base#(int))
blocking_get_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))	The following are all aliased to the above get_peek_export, which provides the superset of these interfaces.
nonblocking_get_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))
get_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))
blocking_peek_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))
nonblocking_peek_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))
peek_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))
blocking_get_peek_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))
nonblocking_get_peek_export	uvm_get_peek_imp#(int, uvm_tlm_fifo_base#(int))

Constructors

function new ( string name, uvm_component parent )

The name and parent are the normal uvm_component constructor arguments. The parent should be null if the uvm_tlm_fifo 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.
