AXI Interconnect LogiCORE IP Product Guide (PG059)

Document ID

PG059

Release Date

2022-05-17

Version

2.1 English

Common Configuration:

•Connectivity Mode: Shared-Address/Multiple-Data (SAMD, as selected by Maximize Performance strategy)

•Protocol: AXI4 or AXI3

•Data Width: 64 or 512 (as noted)

•Read/Write Connectivity: all MI fully connected for read and write

•Thread ID Width: 0 (all SI)

•Address Width: Global = 32; per MI = 16-bit address segment (1 address range)

•Read/write Acceptance: 4

•Read/write Issuing: 8

•Arbitration Priority: 0 (round-robin)

•User Widths: 0

Note: The specifications in these tables are derived by implementing the configured IP in isolation, characterizing clock frequency based on static timing results, and then applying a 10% guardband below the highest constrained clock frequency that meets timing.
