While the write address and write data channel are in same directions, The read address and read data channel are in opposite directions. There needs to be a mechanism where a response is required back from the destination.
In case of read, the response can be the data, but it is actually the response that follows the data on the same read channel, which comes from the destination In case of write, there is NO data flow from destination to source if there was no response channel Now since the response always follows the data, the response channel in case of read is the same as data channel But in case of write, the response channel has to be separate as the ONLY channel from destination to source.
Relation between Write Address and Write Data channels: Write address and write data channels must be presented to slave at the same time.
This means that the write address and write data channel cannot be independent. This is because the address identifies the slave. If the write address and write data channels are not in sync, then the slave will NOT receive the address and corresponding data.
Even if a slave has only one source of read-data, it must assert the RVALID signal only in response to a request for data.
For a write transaction, a single response is signaled for the entire burst, and not for each data transfer within the burst.
While, in a read tran, the slave can signal diff responses for different xfers in a burst. A masters on a fabric need not worry about what ID the other masters s would use, as the ID will be uniquified by the fabric 2. ID width at slave will be larger than the ID width at Master.
A AXI4 Master i.Teams can write their own extensions to hook into the Pipeline job type and make the deployment easier. Meanwhile, job creators can write a plain old Groovy function to define any custom steps that can deploy (or undeploy) artifacts from production.
