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's tool, or obtained from your own power tool (Innergy 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. |
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:
Power monitoring in silicon: Innergy can generate embeddable RTL IPs of the action-power models built for the SoC. These can be used to monitor and control power consumption in real time for power and performance optimization. |
