Detailed Description

contains all data and functions related to axi and usage

In addition to variables like addr,len, id, this alsocontains functions that could be moved into axi_uvm_pkg to save object space. Things like calculating aligned_address from address.

Todo:: : this seq_item is laughably large. Don't judge me, I've seen your 'temporary' code too. ;)

Here is the caller graph for this function:

void axi_seq_item::get_beat_N_data	(	input int	beat_cnt,
		input int	data_bus_bytes,
		ref bit< 7:0 >	data[],
		ref bit	wstrb[],
		output bit	wlast
	)

return beat values for write data and read data channels

given the beat number and how wide the bus is, return field values that can be placed directly on the bus.

Parameters

beat_cnt	which beat inthe burst, starting at 0.
data_bus_bytes	- how wide is the bus (the driver/responder can get this from the interface
data	- data to be put on wdata/rdata busses (dynamic array, depth=data_bus_bytes)
wstrb	- byte strobes, to be put on wstrb bus (dynamic array, depth=data_bus_bytes)
wlast	- just what you think it is.
