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
