The AXI Protocol Checker tracks Read and Write transactions by their ARID and AWID respectively. Therefore, the wider the ID width, the more resources consumed by the Protocol Checker. The transaction information per ID is stored until the transactions are completed, and the depth of the memory is directly related to the number of outstanding transactions that can occur for a given transaction ID.
Important: Configure the core to ensure the core
is not over-monitoring and wasting resources. An ID width greater than six bits can lead
to very large resource utilization by the core.
