Getting Started

Cycle models are compiled directly from Arm RTL and retain complete functional and cycle accuracy. This enables you to confidently make architectural decisions, optimize performance or develop bare metal software.

Performance Optimization with Cycle Models

Instrumented for Analysis

Cycle Models are instrumented to enable detailed debug and analysis. CPU cores enable interactive debug with Arm Development Studio. Additionally, all registers and PMUs are visible along with information related to cache hits, pipeline statistics and much more.

Implementation level accuracy

Cycle Models are compiled directly from the implementation RTL and retain 100% of the functionality and cycle accuracy. Cycle Models can be used in SystemC simulation environments as well as RTL simulators.

Creation of Arm Cycle Models

Cycle Models are available 24 hours a day/7 days a week from Arm’s IP Exchange web portal. This portal enables users to access, configure, compile and manage their own models of Arm IP. Users are then emailed when their model is available for download
