7.3.1. F2H and F2SDRAM Restrictions

Intel® Stratix® 10 uses all of the signaling defined within the ARM® AMBA* AXI* and ACE-Lite* Protocol Specification, except for the AxDOMAIN signaling and AxBURST signaling. The AxUSER bits are not exposed since there is no need to restrict the masters within each bridge path.

FPGA-to-SDRAM direct ( AXI* 4)

  • All operations bypass the CCU and are non-coherent.
  • For all burst transactions, AxBURST must be either ‘b01 (INCR) or ‘b10 (WRAP).

FPGA-to-HPS CCU (ACE-Lite)

  • For all coherent operations, AxDOMAIN[1:0] must be ‘b01, Inner sharable.
  • For all non-coherent operations, AxDOMAIN[1:0] must be ‘b01, Inner sharable.
  • For all burst transactions, AxBURST must be either ‘b01 (INCR) or ‘b10 (WRAP).
