Software Costs Increasing
Primary Design Costs By Process Node
The cost of developing and
qualifying software
increases rapidly with
higher complexity IC
designs
High-performance SoCs
include multiple processor
cores and 100s of IP
blocks

Benefits of using Virtual Prototypes with ARM Fast Models
Time to Market
Early Access to Models
Iterative Development
High performance Models
Find bugs and profile code faster
Starting software development early and parallel development
shortens the design cycle
Models and virtual prototypes available months before silicon.
Start software development early.
Does not need a complete hardware design to start! Start
development on core models and expand the prototype as
hardware design evolves.
Models execute at 50-200 MIPS, Linux boot in under 1 minute.
Enables productive software bring up.
Comprehensive debug and trace interfaces and simple control
make it easier to find and fix problems early.
Easy to use, maintain and distribute No hardware to build, support and maintain
