Enumeration Type Documentation

enum axi_protocol_version_t

Version 3 or Version 4.

A few differences:

AXI4 has no WID
if burst_type=e_INCR, then AxLEN can be to 256[2**8], instead of just 16 [2**4]

Enumerator
e_AXI3
e_AXI4

Definition at line 52 of file axi_uvm_pkg.sv.

Function Documentation

automatic void ar_from_class	(	ref axi_seq_item	t,
		output axi_seq_item_ar_vector_s	v
	)

take values from an axi_seq_item and stuff into a axi_seq_item_ar_vector_s

This funcion returns a ready-to-be used struct so arlen and araddr are calcuated in this function.

Parameters

t	- The axi_seq_item is passed by reference

Returns: v - packed struct of type axi_seq_item_ar_vector_s

Definition at line 193 of file axi_uvm_pkg.sv.

Here is the caller graph for this function:

automatic void ar_to_class	(	ref axi_seq_item	t,
		input axi_seq_item_ar_vector_s	v
	)

Pull values out of a axi_seq_item_ar_vector_s and stuffs them into an axi_seq_item.

t.len is converted from arlen into a byte len. It uses burst_size (bytes per beat) * beats_per_burst to give a maximum byte length.

Parameters

t	- an axi_seq_item

Returns: v - a packed struct of type axi_seq_item_ar_vector_s

	)

Pull values out of axi_seq_item and stuff into a axi_seq_item_aw_vector_s.

This funcion returns a ready-to-be used struct so awlen and awaddr are calcuated in this function.

Parameters

t	an axi_seq_item

Returns: v a packed struct of type axi_seq_item_aw_vector_s
