3.1.2. PSS Subsystem Components

The following table lists the support status of components integrated into the PSS subsystem. The table also indicates any limitation in the component and the object created in the HPS Intel® Simics® model of the Intel Agilex® 5 E-Series device.

Component Supported? Limitations | Objects

Yes
  • Limitation: Modeled as a memory map with no firewall support.
  • Object: system.board.fpga.soc_inst.hps_subsys.agilex_hps.noc
