+          Precondition:
+            - Randomize the number of RACL policies and randomize its default policy values.
+            - Randomize the policy selection vector of the CSRs.
+            - Randomize the ErrorRsp parameter.
+            - Shuffle the list of CSRs first to remove the effect of ordering.
+
+          Verify the correct access for each CSR:
+            - Loop through each CSR and perform a read and write request using a
+              random RACL role and random CTN UID value.
+              If the request is allowed:
+                No TL-UL error is expected.
+              else if the request is denied:
+                - Verify the error log matches:
+                  - error_log_o.valid = 1
+                  - error_log_o.overflow = 0
+                  - error_log_o.racl_role = <role that caused the error>
+                  - error_log_o.ctn_uid = <ctn uid that caused the error>
+                - Verify that a write has no effect.
+                - Verify a read returns data with 0xFFFFF (all bits set to 1).
+                - If ErrorRsp = 1:
+                  - Verify a TLUL error is returned.
