memory::new	(	string	name = "memory",
		uvm_component	parent = null
	)

Doesn't actually do anything except call parent constructor

Reads from memory.

uses an associative array. If reading from unwritten address, 'z is returned.

Referenced by axi_monitor::read_address(), and seq_item_check().

Here is the caller graph for this function:

automatic bit memory::seq_item_check	(	ref axi_seq_item	item,
		input bit< ADDR_WIDTH-1:0 >	lower_addr,
		input bit< ADDR_WIDTH-1:0 >	upper_addr
	)

Compares an axi_seq_item's data and burst_type against expected matching memory contents.

This function takes into account fixed, incrementing and wrapped burst types. That includes accounting for burst_size.
