5.15.1. ACE-Lite Transaction Support and Limitations
Platform Designer's ACE-Lite interface comprises all the signals specified in the AMBA 4 AXI specification. However, there are limitations on the extent of transactional support that Platform Designer interconnect provides for ACE-Lite transactions. Platform Designer interconnect supports narrow to Wide, Wide to narrow and same Data width, ID width, and Address width adaptation for point-to-point connection (1-manager, 1- subordinate).
| Transaction Type | Supported Transactions | 
|---|---|
| Non-snoop transactions | WriteNoSnoop, ReadNoSnoop | 
| Coherent transactions | WriteUnique, ReadOnce | 
| Transaction Type | Unsupported Transactions | 
|---|---|
| Barrier transactions | ReadBarrier, WriteBarrier | 
| Cache Maintenance transactions | CleanShared, CleanInvalid, MakeInvalid | 
| Coherent transactions | WriteLineUnique | 
Even though direct ACE-Lite to AXI4 connection is not supported, you can use the Cache Coherency Translator IP to perform the connection between an AXI4 manager to an ACE-Lite subordinate. Refer to Cache Coherency Translator Intel FPGA IP in Embedded Peripherals IP User Guide for more details.
