Cloud native EDA tools & pre-optimized hardware platforms
Traditional tools and methods for embedded software development are insufficient to address today’s complex embedded systems, especially multicore chips and SoCs, as well as their aggressive development timelines.
A virtual prototype is an executable software model that runs on a host system. It emulates the hardware, including CPU instruction sets, memory maps, registers, and interrupts, at a sufficient level that can be tailored for software development. From a software perspective it is binary-compatible with the hardware being emulated, allowing users to run unmodified binary images of the entire software stack that includes everything from low-level device and firmware to operating systems to middleware and, finally, to the application being developed. It is a complete functional representation of the target system on which to develop software.
A virtual prototype abstracts away hardware details that are irrelevant to software developers. Using instruction set simulators, the virtual prototype executes embedded target code on standard PCs. 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.
The simulation speed is very high to enable the interactive execution of large software stacks, such as applications running on top of AUTOSAR or Android OS. Virtual prototypes use virtual and real-world I/O to connect to real-world interfaces like USB, PCIe, Ethernet, and serial devices.
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.
