Version

2.1 English

Common Configuration:

•Connectivity Mode: SASD (Minimize Area strategy)

•Protocol: AXI4-Lite

•Data Width: 32

•Read/Write Connectivity: all SI and MI read/write

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

•Arbitration Priority: 0 (round-robin)

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.
