SMU Top-Level Integration

The System Management Unit (SMU) comprises three peer subsystems: the System Management Controller (SMC), the Debug & Test Ports (DTP), and the Security Processor (SEP). The subsections below describe each subsystem’s interfaces independently, followed by the SMU Composition section that explains how they are wired together inside the SMU and how to select between the smu.sv logic-level core and the smu_wrapper.sv reference integration.
