execute_stream_ready()
This procedure executes a stream ready by placing the ready argument value onto the TREADY
signal.
Example
-- Assign TREADY = '0'. This will consume one cycle.
execute_stream_ready(0, bfm_index, axi4stream_tr_if_0(bfm_index));
-- Two clock cycle wait.
for i in 0 to 1 loop
wait_on(AXI4STREAM_CLOCK_POSEDGE, bfm_index,
axi4stream_tr_if_0(bfm_index));
end loop;
-- Assign TREADY = '1'.
execute_stream_ready(1, bfm_index, axi4stream_tr_if_0(bfm_index));
Prototype procedure execute_stream_ready
(
ready : in integer;
non_blocking_mode : in integer; -- Optional
bfm_id : in integer;
signal tr_if : inout axi4stream_vhd_if_struct_t
);
Arguments ready The value of the TREADY signal
non_blocking_mode (Optional) Controls the blocking or nonblocking mode of the
procedure.
0 = blocking (default)
1 = nonblocking
bfm_id BFM identifier. Refer to “ Overloaded Procedure Common
Arguments ” on page 87 for more details.
tr_if Transaction signal interface. Refer to “ Overloaded Procedure
Common Arguments ” on page 87 for more details.
Returns None
