AXI Crossbar Performance: SASD, AXI4-Lite Protocol - 2.1 English - PG059

AXI Interconnect LogiCORE IP Product Guide (PG059)
Document ID
PG059
Release Date
2025-12-19
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.
