BFM procedures
- avalon_mm_write ( constant addr_value : in unsigned;
constant data_value : in std_logic_vector;
constant msg : in string;
signal clk : in std_logic;
signal avalon_mm_if : inout t_avalon_mm_if;

constant msg_id_panel : in t_msg_id_panel := shared_msg_id_panel;
constant config : in t_avalon_mm_bfm_config := C_AVALON_MM_BFM_CONFIG_DEFAULT ) return ()
Description
This procedure could be called from an a simple testbench or
from an executor where there are concurrent BFMs - where
all BFMs could have different configs and msg_id_panels.
From a simplified testbench it is not necessary to use arguments
where defaults are given, e.g.:
avalon_mm_write(addr, data, msg, clk, avalon_mm_if);
