In AXI the master transaction is started by Address validation, so if the Address (AWADDR/ARADDR) with its valid (AWVALID/ARVALID) is there then the master is awaiting for the ready (AWREADY/ARREADY) from the slave side. So by checking the Address valid I think we can give the permission for the master to go for the transaction.

Hey thanks !!

my approach for the arbitration is same. i am checking valid signal only. Actualy someone asked me this question in a interview and i answerd the same as u mentioned but he literally laughed at my answer that arbitation in AXI is based on valid signal generated by master. so that y i just want to confirm this.
