Detailed Description

Writes to memory over AXI, backdoor readback, then AXI readback.

miscompares are flagged.

bit axi_seq::compare_items	(	ref axi_seq_item	write_item,
		ref axi_seq_item	read_item
	)

Compares the write-item with the corresponding read_item.

THis isn't the same as a do_compare() method in the axi_seq_item because the readback is depenent on which burst_type Although it could probably exist as aseperate method in the seqitem.

Parameters

write_item	- the original item
read_item	- the item after memory readback

Returns

True if no miscompares, false if miscompares

axi_seq::new

(

string

name = "axi_seq"

)

Constructor.

Doesn't actually do anything except call parent constructor

References max_burst_size.

void axi_seq::set_transaction_count

(

int

count

)

How many transactions?

This method sets how many transactions to send (Write Address, Write Data, Write Response) is one traction (Read Address, Read Data) is one transaction

Parameters

count

- how many transactions to send
