Procedures

write_address_channel_write

This procedure writes adress on the write address channel

When the write is completed, a log message is issued with ID_CHANNEL_BFM

write_data_channel_write ( constant wdata_value : in std_logic_vector;
constant wstrb_value : in std_logic_vector;
constant msg : in string;
signal clk : in std_logic;
signal wdata : inout std_logic_vector;

constant scope : in string := C_SCOPE;
constant msg_id_panel : in t_msg_id_panel := shared_msg_id_panel;
constant config : in t_axilite_bfm_config := C_AXILITE_BFM_CONFIG_DEFAULT ) return ()

Description

write_data_channel_write

This procedure writes data on the write data channel

When the write is completed, a log message is issued with ID_CHANNEL_BFM

write_response_channel_check ( constant msg : in string;
signal clk : in std_logic;
signal bready : inout std_logic;
signal bresp : in std_logic_vector(1 downto 0);

constant msg_id_panel : in t_msg_id_panel := shared_msg_id_panel;
constant config : in t_axilite_bfm_config := C_AXILITE_BFM_CONFIG_DEFAULT ) return ()

Description

write_response_channel_check

This procedure checks the write response on the write response channel

If the received response was inconsistent with config.expected_response,
an alert with severity config.expected_response_severity is issued.
When completed, a log message with ID id_for_bfm is issued.

read_address_channel_write ( constant araddr_value : in std_logic_vector;
constant msg : in string;
signal clk : in std_logic;
signal araddr : inout std_logic_vector;

constant config : in t_axilite_bfm_config := C_AXILITE_BFM_CONFIG_DEFAULT ) return ()

Description

read_address_channel_write

This procedure writes adress on the read address channel

When the write is completed, a log message is issued with ID_CHANNEL_BFM

constant ext_proc_call : in string := "" -- External proc_call. Overwrite if called from another BFM procedure ) return ()

Description

read_data_channel_receive

This procedure receives read data on the read data channel,
and returns the read data

If the received response was inconsistent with config.expected_response,
an alert with severity config.expected_response_severity is issued.

read_data_channel_check ( constant rdata_exp : in std_logic_vector;
constant msg : in string;
signal clk : in std_logic;
signal rready : inout std_logic;
signal rdata : in std_logic_vector;

constant msg_id_panel : in t_msg_id_panel := shared_msg_id_panel;
constant config : in t_axilite_bfm_config := C_AXILITE_BFM_CONFIG_DEFAULT ) return ()

Description

read_data_channel_check

This procedure receives and checks read data and
read response on the read data channel

If the received data is inconsistent with rdata_exp,
an alert with severity alert_level is issued.
If the received data is correct, a log message with ID id_for_bfm is issued.
