About system models

Real-Time System Models (RTSMs) enable development of software without the requirement for actual hardware. The software models provide Programmer’s View (PV) models of processors and devices. The functional behavior of a model is equivalent to real hardware.

Absolute timing accuracy is sacrificed to achieve fast simulated execution speed. This means that you can use the PV models for confirming software functionality, but you must not rely on the accuracy of cycle counts, low-level component interactions, or other hardware-specific behavior.

System models are supplied as a Component Architecture Debug Interface (CADI) shared library, and are loaded by any environment compatible with the CADI API. Such environments include:
