Silicon Analytics Inc. - pTunerOPUS™ is an EDA tool providing power optimization within your existing design flow and works without altering the existing floorplan.


pTunerOPUS™ can be used post-synthesis & pre-layout for a quick estimate and optimization for power or post-layout, before final verification & pre-fabrication optimization run.

pTunerOPUS™ combines advanced mathematical techniques with proprietary models and algorithms to deliver best-in-class optimization results.


Silicon Analytics Inc. will engage under a license or services model, depending on our customers' design needs.


Supports hierarchical and flattened  netlist. Thus, individual blocks can be  optimized separately and custom IP  blocks  can be included as “black-boxes” into the  design flow.

Low execution time provides rapid feedback  during tradeoff analysis; resulting in better  design choices.

Power savings are independent-of & additive to existing commercial optimization tools.

Takes standard  design  synthesis files to optimize independently for dynamic and leakage or total power.

Supports multi-threshold standard cell libraries.

Supports multiple primary and generated clocks within a design.

Does not change circuit structure, so previously  generated floorplan  can be re-used.

Supports  command-line  as well as graphical user interface.
