4.3.4.3.2.1. ACE5-Lite Subordinate Interface

ACE5-Lite interface for each TBU instance on which transactions are received from the peripherals.

Optional signals are included as part of the ACE5-Lite protocol to support the following features:

  • Wakeup signals
  • Untranslated transactions
  • Cache Stash transactions

For Agilex™ 5, only untranslated transaction (Stream IDs) and Cache Stash Transaction interfaces are supported. The wakeup is tied to 1’b1 as to say that SMMU is always active after power-on.
