What Arm Fast Models is

Arm Fast Models are programmer’s-view models of Arm CPU and System IP for software development before hardware implementations are available. They support work on low-level software such as operating system kernels and device drivers, and cover coprocessor registers, exception levels, translation tables, and cache. Supported targets include Cortex-A, Cortex-R, Cortex-M, and Arm System IP. SystemC interfaces can connect the models to third-party models to form virtual SoC prototypes. A virtual debug connection is supported by many debug vendors and is intended to keep debugging consistent between hardware and software targets. Scripting interfaces support automation, continuous integration, and validation farms. Arm lists early development, system optimization, testing and validation, and hardware/software co-design as use cases. Linux hosts are supported on AArch64 and x86; Windows hosts are supported on x86 and require Visual Studio 2019 version 16.11 or later, excluding Express and Community editions. The product is license managed, and a 30-day trial license can be requested by email with the CPU models specified. Pricing is on request.

Who it suits

It suits teams developing or validating Arm software before the target hardware is available, particularly those working on operating system kernels or device drivers. It also fits teams building virtual SoC prototypes or automating validation.
