4.3.4.3.2.2. ACE-Lite Manager Interface

The Manager ACE-Lite interface provides the connection between the TBU instances and the NoC. Addresses on this interface have been translated by the MMU.

Optional signals are included as part of the ACE-Lite protocol to support the following features:

  • Wakeup signals
  • Untranslated transactions

When a SLVERR or DECERR is received in response to a downstream transaction, the error is passed to the Subordinate interface.

For Agilex™ 5, only Untranslated Transaction (Stream IDs) are supported.

TBU low-power interface is not used for Agilex™ 5, Wakeup signal does not have any impact to the TBU functionality. So, it is tied to 1’b1 just to make the design active all the time after power-on.
