Fast Models – Arm Developer

Components in a Virtual Prototype

A complete virtual prototype of a system contains more than just an Instruction Set Simulator. A full system consists of:

Fast, accurate models of cores, subsystems or systems
SystemC interface for integration with EDA tools and other IP blocks
APIs for debug (CADI) and trace (MTI), allowing full control and an interface to DS-5, MDK and 3rd party debug tools
Python based scripting for runtime control, checking and reporting
Visualization, file system access, peripherals and networking from virtual I/O
Fully compatible Linaro software stacks, from boot code to Linux and Android OS support

Software Development with Fast Models

Complete & Accurate

Fast Models are available for all Cortex processors, CCI and CCN interconnect, as well as other system IP. Fast Models are functionally accurate, so banked and co-processor registers, exception levels, translation tables and cache coherency are all available to programmers.

Hybrid Simulation

Connect a CPU subsystem to peripherals on hardware emulators via AMBA transactors for emulation acceleration. Compatible with Cadence, Mentor Graphics and Synopsys emulators for maximum flexibility in your software development and IP validation process.

Save and Restore

Checkpointing allows you to save your simulation once the OS has booted, so that you can restart from there and jump quickly back into your software. For regression testing, multiple simulations can be restarted from a single checkpoint.

Timing Annotation

Fast Models interact with TLM approximately timed models for high level software performance estimation. This helps to give an idea of how software will perform on the real device, saving software development time further into the project.

Fast Models Portfolio

Arm releases models of our IP to lead partners at an early stage, so please contact us for more information on upcoming Fast Models.

Fixed Virtual Platform Downloads

Fixed versions of Fast Models are also available, giving software developers a ready-to-use model of a complete Arm system. They can be downloaded, licensed individually and imported into DS-5 for ease of use. Fixed Virtual Platforms are a convenient way of testing software without needing to wait for development boards to become available.
