​With Innergy Quarx-IQ

​
Find and Fix Power Issues
​

in Minutes

Automatically finds DUT's most power correlated signals 

Quarx-IQ uses Local AI algorithms (running on customer compute servers without any need to connect to the internet) to scan millions of signals in your DUT and find the optimum set which is most correlated to power consumption.

The selected signal set is highly optimized, often less than 0.5% of all the signals in the DUT. This helps the engineers to quickly locate the root causes of power consumption and work on solutions.

Quarx-IQ then builds a power model based on these signals by intelligently grouping and tracking them. 

Models run 30x - 100x faster
​

Our patented technology builds the AI based power models to run at a high level of abstraction without requiring gate simulations. This means the models run in a fraction of the time required with traditional tools.

Embeddable RTL for real-time power monitoring 

​​Innergy Quarx can generate synthesizable, embeddable RTL of the power models built for your design. These can be used to monitor power in real time, providing feedback to your software or hardware.
​
​Power and performance balance may be achieved within your system using the fine-grained information from the embedded power monitors.

The monitors are typically < 1% of the area of the DUT, with less than 0.5% of the power consumption of the DUT.
​

Models are highly accurate 
 


​​Innergy's models have been consistently benchmarked against leading signoff power tools. Our models achieve a typical accuracy of 85%-95% or better when compared to the power data used to build the models.

Early and quick 'what-if' power exploration            

Action-power models may be used to explore the power effects of changes in architecture, design parameters or throughput.
Innergy power models come with built-in control 'knobs' to change voltage, frequency, throughput (by changing action densities), and much more.
​
​Since 'what-if' exploration relies on model generated scenarios, you can complete most exploration tasks in under a minute.

Both brand new designs as well as evolutionary designs are supported.

Following are a few examples of what you can explore early in your design process.
  • High/medium/low traffic impact on power
  • Power v/s performance analysis
  • Voltage and frequency scaling
  • Clock gating changes
  • Changes to architecture

Customer results for power vs performance 'what-if' analysis  (Memory Controller)

For a custom protocol memory controller block used in a large packer processor, Innergy estimated a 24.9% reduction in peak power with only 3.6% nominal performance loss.
These results were validated in simulations at full chip level.
