get_write_addr_data()

September 2013

AXI4 Example

-- Wait for the write data burst to complete for the tr_id transaction.

get_write_data_burst(tr_id, bfm_index, axi4_tr_if_1(bfm_index));

-- Get the burst length of the tr_id transaction.

get_burst_length(burst_length, tr_id, bfm_index,

axi4_tr_if_1(bfm_index));

-- Loop for the length of the data burst.

for i in 0 to burst_length loop

-- Get the address, first data byte and byte length for the

-- data phase (beat)

get_write_addr_data(tr_id, i, 0, byte_length, addr, data, bfm_index,

axi4_tr_if_1(bfm_index));

-- Store the first data byte in the slave memory using the

-- slave test program do_byte_write procedure

do_byte_write(addr, data);

-- Loop for the number of bytes in the write data phase (beat)

-- given by the byte_length

if byte_length > 1 then

for j in 1 to byte_length-1 loop

-- Get the remaining bytes of the write data phase (beat)

-- and store thenm into the slave memory.

get_write_addr_data(write_trans, i, j, byte_length, addr, data,

index, axi4_tr_if_1(index));

do_byte_write(addr, data);

end loop;

end if;

end loop;
