Hi experts,
I get the following information about NSAID from TZC-400 trm.The Non-Secure Access IDentity (NSAID) input identifies the source interface of a transaction to a filter unit. When in Non-secure state the NSAID inputs identify the master that is the source of the access. The filters use the NSAID inputs to filter Non-secure accesses based on the source of the access. NSAIDR<x>[3:0] Master Identifies the source of Non-secure read accessesNSAIDW<x>[3:0] Master Identifies the source of Non-secure write accesses
And I am confused about NSAID. Why not use AXI ID signal AxID to identify the master that is the source of the access?How to control NSAIDR<x>[3:0] and NSAIDW<x>[3:0] signals?
Best Wishes,
Thanks.
