The Golden NoC CDO (Configuration Data Object) in Versal devices verifies configuration of the Network on Chip (NoC) for the boot process. Golden NoC CDO verifies security requirements of the user generated boot CDOs in SSI technology devices. Verification of boot-time configuration is crucial for ensuring secured data flow and connectivity within the Versal architecture. The following are some key usage:
Initial Configuration
The Golden NoC CDO sets up the initial configuration of the NoC, ensuring that all data paths and connections are correctly established for the system to function properly.
System Stability
Proper configuration of the NoC ensures system stability and reliability during boot-time, providing deterministic boot path across variety of custom designs.
