[SOLVED] Transaction ID implementation in axi amba bus

[u24c02]

HI


Can you help me how to understand transaction ID ?

I have attached one example image.

I heard that Transaction ID = <Master ID, Channel ID>
But I didn't quite understand,
Q1) What is the Master ID and Channel ID from attached image?
Q2) do those ID set at the initial early stage? can you let me know exactly how to set the ID?
Q3) Practically, do we use Transaction ID ? or something else ?

I advise you read the AXI4 spec a few times (not just skim over it), it's described in the spec.

I wonder that why you refer to axi4 not axi3?

Because it is the most updated version from ARM. Better to use the latest ones.
