The following features present on the hardware version of the Emulation Baseboard are only partially implemented in the Real-Time System Models:
Partial implementation means that some of the components are present but the functionality has not been fully modeled. If you use these features, they might not work as you expect. Check the model release notes for the latest information.
The EB RTSMs implement the PL041 AACI PrimeCell and the audio CODEC as in the EB hardware, but with a limited number of sample rates.
