System peripherals are modeled at the transaction level with just enough detail to run unmodified software images; for example, register behavior is accurate, whereas timing is not. Early availability, binary compatibility, and high performance enable virtual prototypes to be used to develop, debug, integrate, and validate system software long before actual physical hardware is available, and in many cases even before the chip design is complete.

Virtual prototypes are best deployed as soon as possible in the development cycle, such as during:. BMS is technology dedicated to the oversight of a battery pack. Cloud Synopsys in the Cloud.

A critical part of starting early on the development of the virtual prototype is the development of the models and the connection of the instruction-accurate processor models.
An automatic model generation tool was used to create the register stub models for all the peripherals by extracting information for the reference specification, as shown in Figure 3.
The register stubs, tests, and documentation are automatically generated. Figure 3: Register stub models automatically generate the register stub, tests, and documentation. A register stub model includes all the register interfaces of a peripheral, but not the functional behavior. The functional behavior is added by the model developer, extending the stub model to a fully functional model.
Oftentimes, early software development can begin with stub models and expand as functionality is added. Source code debug is required for effective embedded software development, but the virtual prototype environment can extend conventional single stepping by using fast processor models that not only allow single stepping, but CPU register viewing and instruction and register trace recording as well. Because the processor models are integrated with a simulator, single stepping software on multiple cores is possible.
As a result, the virtual prototype offers true multicore debugging, where developers can set source breakpoints on any software instruction running on any core. When the breakpoint triggers, they can see not only the state of the core executing the software, but also the state of the other cores in the system. Many virtual prototyping solutions also extend the concept of register viewing to provide not only the CPU register view, but also register views of all the programmable devices in the system.
Source code debug and register view tools highlight register changes when a software breakpoint is triggered and, if needed, the virtual prototype simulator can maintain a synchronized view of each of these registers at the time of a breakpoint on any core or register change.
