1.2.2. About the EB Real-Time System Models

The Real-Time System Model components for the EB Reference System are:

The EB RTSM also includes virtual components:

The Real-Time System Models for the EB Reference System are hierarchical models that consist of:

The EB RTSMs provide a functionally-accurate model for software execution. However, the model sacrifices timing accuracy to increase simulation speed. Key deviations from actual hardware are:

Many components can be configured at instantiation time. See EB model configuration parameters.

For more detail on the differences, see Differences between the EB and CoreTile hardware and the models.

Top-level view of an EB model

A block diagram of the top-level model for an EB with a Cortex-A8 CoreTile is shown in Figure 1.1.

CoreTile component

The CoreTile component provides the processor version and the associated ports that enable interconnection with other top-level components. The block diagram of the model for the Cortex-A8 CoreTile is shown in Figure 1.2.
