•Description: Controls AXI register slice insertion on SI.
°If None (0) is selected, no register slice is inserted.
°If Outer (1) is selected, a register slice is inserted at the SI side of the SI coupler cells hierarchy.
°If Auto (2) is selected, a register slice is automatically inserted in the SI coupler cells hierarchy if SI coupler cells with common timing paths are detected.
°If Outer and Auto (3) is selected, a register slice is inserted at the SI side of the SI coupler cells hierarchy and an additional register slice can be inserted if SI coupler cells with common timing paths are detected.
For the AXI4-Lite protocol, use LIGHT_WEIGHT for all channels. For other protocols, use FULLY_REGISTERED on W and R channels and use LIGHT_WEIGHT on AW, AR and B channels.
