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

Who it suits
Fast Models suits software and hardware teams developing for Arm targets before physical implementations are ready. It is relevant when virtual prototyping, debugging, automation, or validation-farm workflows are needed.
Verdict
Fast Models provides detailed Arm processor and System IP models for early software work and virtual system development. Its managed licensing and host requirements should be checked before adoption.
