The Quest for Optimal PPA in Semiconductor Design

Optimizing Power, Performance, and Area (PPA) is a pivotal challenge in semiconductor design. As chips grow increasingly complex, balancing these factors becomes a formidable task. Traditional approaches might require trade-offs — boosting performance could mean higher power consumption and a larger silicon area. However, new tools like footprint by Axiomise are transforming how the industry approaches PPA optimization, streamlining design processes without the usual sacrifices.

Uncovering Redundant Components

One of the key challenges in optimizing PPA is identifying underutilized or redundant components in vast silicon designs. Conventionally, structural coverage methods like unreachability analysis have been employed to spot inefficient components. However, these methods often miss elements that are technically reachable but redundant, resulting in wasted power and resources.

footprint leverages formal property verification to automatically detect these redundancies. It classifies components as fully redundant if they do not contribute to any logical operations within the design. Unlike traditional reachability analysis, this method dives deeper, identifying both fully and partially redundant elements that may slip past synthesis processes.

The Mechanism Behind Footprint

footprint operates as part of the axiomiser platform, which brings over two decades of expertise in formal verification to the table. This tool integrates seamlessly with existing formal tools and requires no testbench or stimulus development from users. It enhances user efficiency by speeding up the detection of redundancies, allowing engineers to maintain focus on core design requirements.

By automatically pinpointing underutilized elements, footprint helps designers make informed decisions faster. This early identification process can accelerate synthesis, preventing the inclusion of unnecessary components that could potentially degrade PPA.

Transforming the Chip Design Landscape

footprint's ability to process designs with hundreds of millions of gates is a testament to its robustness. It paves the way for formal verification to become a standard practice, offering comprehensive coverage of the state space and enhancing chip designers' capabilities.

Moreover, footprint is designed with user-friendliness in mind. Its interactive interface enables easy result regeneration following design iterations, emphasizing clarity and relevance. Such features ensure efficient identification of wasted resources and potential bugs early in the design cycle, paving the way for smoother mitigation processes.

Embracing Innovations in Design

As the semiconductor industry strives for more efficient, high-performance chips, tools like footprint represent a significant advancement. By identifying and eliminating inefficiencies, they enable designers to push the boundaries of what's possible without compromising on PPA. This shift towards more precise and automated verification processes is essential for meeting the demands of modern electronics.
