6.1. Design Example Simulation Features

The simulation design example allows the operation of the MIPI DSI-2 IP to be observed and tested in a loopback system. The simulation produces video data and supplies it to the DSI TX IP and loops the output packet data back into a DSI RX model before comparing the recovered video data with the input data. Two variants of the system are provided, which are described below. In each case, the configuration and operation of the whole system is adapted to the user’s configuration of the MIPI DSI-2 TX IP as the design example simulation is generated.
Figure 18. Full Simulation Block Diagram

The full simulation variant sends video through the MIPI DSI-2 TX and MIPI D-PHY TX and loops back the MIPI serial signals to the MIPI D-PHY RX IP. It thens recovers and checks the video data. This gives an accurate view of the operation of the MIPI subsystem to the MIPI D-PHY external I/O level.

Figure 19. Fast Simulation Block Diagram

The fast simulation variant ignores the MIPI D-PHY IPs and performs loopback at the PPI level. A simple PPI loopback module replaces the MIPI D-PHY IPs and adapts from the PPI TX to PPI RX signaling while mimicking the MIPI D-PHY flow control. This allows the simulation to run much faster and generally provides a sufficient view of the way that the MIPI DSI-2 TX IP functions. The operation of the simulation is otherwise identical to the full simulation variant.
