AXI4 firewall
Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1
Address-range access filter for AXI4 with per-region read/write, privilege and secure-attribute (AxPROT) checks, error responses for blocked transactions and violation logging.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
