Member Function Documentation

task axi_responder_seq::body

(

)

Does all the work.

1. Creates constrained random awready toggle pattern
2. Sends it
3. Creates constrained random wready toggle pattern
4. Sends it
5. Creates constrained random arready toggle pattern
6. Sends it
7. In a forever loop, waits for TLM packets from monitor sends them on to responder

Here is the call graph for this function:

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

inherited

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

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
