module. For example, the code extract below shows the AXI3 monitor BFM with the address,
ID and data signal widths defined in module top() and passed in to the monitor BFM
mgc_axi_monitor parameter port list:
module top ();
parameter AXI_ADDRESS_WIDTH = 24;
parameter AXI_RDATA_WIDTH = 16;
parameter AXI_WDATA_WIDTH = 16;
parameter AXI_ID_WIDTH = 4;
mgc_axi_monitor #(AXI_ADDRESS_WIDTH, AXI_RDATA_WIDTH, AXI_WDATA_WIDTH,
AXI_ID_WIDTH) bfm_monitor(....);
Note
In the above code extract the mgc_axi_monitor is the AXI3 monitor BFM interface.
The following table lists the parameter names for the address, ID and data signals, and their
default values.
A monitor BFM has configuration fields that you can set via the set_config() function to
configure timeout factors, slave exclusive support, setup and hold times, etc. You can also get
