Innergy Quarx Action-Power Models

Breakthrough Speed and Accuracy

Action-Power Model Building

Innergy Quarx builds statistical power models that identify actions within your design and the power consumed by those actions.

Actions are identified from a few key signals in the DUT's (Design Under Test) activity file (FSDB/VCD).

Power is obtained from DUT's cycle-based power data. This data may be generated using Innergy Quarx, or obtained from your own power tool (Innergy Quarx works with all leading power tools).

Examples of Actions:
Actions can be small or large duration.
Small duration actions: memory transaction, opcode execution, a table lookup etc.
Large duration actions: packet routing configuration change, or an image processing algorithm change etc.

Action-Power Model Usage

Action-power models may be used in simulation or for early 'what-if' power exploration. Models forecast power without needing any time- consuming gate simulations.

RTL Simulation: Forecast power quickly and accurately for long running tests. For example: a long running block or full chip test
Emulation: Full chip emulation activity file (FSDB/VCD)
Software simulation: Activity trace from an Instruction Set Simulator

Early 'what-if' power exploration: Use model-generated power simulation to explore various 'what-if' power exploration scenarios:

High/medium/low traffic impact on power
Power v/s performance analysis
Voltage and frequency scaling
Clock gating changes
Changes to architecture

User Experience

Model build process is efficient

Easy integration with your existing tools

We have made our build process very efficient by requiring few user inputs, and automation.
Typical model build duration is a few hours for a major design block.

We work with all leading vendors in the EDA world to provide seamless integration into your tool flow.
