In the age where data reigns supreme, the semiconductor industry stands on the cusp of revolutionary change, redefining complexity and productivity through a lens crafted by artificial intelligence (AI). The intersection of AI and the semiconductor industry is not merely an emerging trend—it is the fulcrum upon which the next generation of technological innovation balances. Semiconductor companies are facing a critical juncture where the burgeoning complexity of chip designs is outpacing the growth of skilled human resources. This is where the infusion of AI-powered data analytics catalyzes a seismic shift in the industry’s approach to efficiency and productivity.

AI in semiconductor design: A revolution beckons

With technological leaps like 5G, AI, and autonomous vehicles driving chip demand, the status quo for semiconductor design is no longer sustainable. Traditional design methodologies fall short in addressing the challenges presented by these new technologies, and the need for a new approach is non-negotiable. AI, with its capacity to process massive datasets and learn from patterns, offers a revolutionary solution. Gathered with vast amounts of electronic design automation (EDA) data, machine learning algorithms can pave an efficient path through design complexities.

Navigating the complexity of EDA data with AI

The core of semiconductor design lies in the complexity of EDA data, which is often disparate, unstructured, and immensely intricate, existing in various formats ranging from simple text to sophisticated binary machine-readable data. AI presents a beacon of hope in taming this beast by enabling the industry to store, process, and analyze data with unprecedented efficiency.

AI-enabled data analytics offer a path through the labyrinth of EDA complexity, providing a scalable and sophisticated data storage and processing solution. By harnessing AI’s capabilities, the semiconductor industry can dissect, organize, and distill data into actionable insights, elevating the efficacy of chip design processes.

Leveraging AI in design excellence

Informed decisions are the cornerstone of successful chip design, and the fusion of AI-driven analytics with semiconductor engineering marks a watershed moment in the industry. AI’s ability to comprehend and process unstructured data at scale enables a deeper understanding of design challenges, yielding solutions that optimize SoCs’ power, performance, and area (PPA).

AI models, fed by fragmented data points from EDA compilation, can predict bottlenecks, performance constraints, or power inefficiencies before they impede the design process. This foresight empowers engineers with informed design decisions, fostering an efficient and anticipatory design culture.

Reimagining engineering team efficiency

One of the most significant roadblocks in the semiconductor industry has been aligning designer resources with the exponential growth of chip demand. As designs become complex, they evolve into multifaceted systems on chips (SoCs) housing myriad hierarchical blocks that accumulate vast amounts of data throughout the iterative development cycle. When harnessed effectively, this data possesses untapped potential to elevate the efficiency of engineering teams.

Consolidating data review into a systematic, knowledge-driven process paves the way for accelerated design closure and seamless knowledge transfer between projects. This refined approach can significantly enhance the productivity of engineering teams, a crucial factor if the semiconductor industry is to meet the burgeoning chip demand without exponentially expanding design teams.

Ensuring a systemic AI integration

For the full potential of AI to be realized, a systemic integration across the semiconductor ecosystem is paramount. This integration spans the collection and storage of data and the development of AI models attuned to the industry’s specific needs. Robust AI infrastructure, equipped to handle the diverse data formats, is the cornerstone of this integration. AI models must complement it and be fine-tuned to the peculiarities of semiconductor design, ensuring that the insights they produce are accurate and actionable.

Cultivating AI competencies within engineering teams

As AI plays a central role in the semiconductor industry, it highlights the need for AI competencies within engineering teams. Upskilling the workforce to leverage AI tools and platforms is a critical step toward a harmonized AI ecosystem. This journey toward proficiency entails familiarization with AI concepts and a collaborative approach that blends domain expertise with AI acumen. Engineering teams adept at harnessing AI can unlock its full potential and become pioneers of innovation in the semiconductor landscape.

The purpose of the verification plan, or vplan as we call it, is to capture all the verification goals needed to prove that the device works as specified. It’s a big responsibility! Getting it right means having a good blueprint for verification closure. However, getting it wrong could result in bug escapes, wasting of resources, and possibly lead to a device failing altogether. With the focus on AI-driven verification, the efficiency and effectiveness of verification planning are expected to improve significantly.

There are several key elements needed to create a good vPlan. We will go over a few below.

Accurate verification features are needed for verification closure

The concept of divide and conquer suggests that every complex feature can be broken down into sub-features, which in turn can be further divided. Verisium Manager’s Planning Center facilitates this process by enabling users to create expandable/collapsible feature sections, a crucial capability for maintaining quality. Not having this key capability can put quality at risk.

Close alignment to the functional specification

Close adherence to the functional specification is crucially linked to the first point. Any new features or changes to existing ones should prompt immediate updates to the vPlan, as failing to do so could affect verification quality. The Planning Center allows users to associate paragraphs in the specification to the vPlan and provides notifications of any corresponding alterations. This allows users to respond by adjusting the vPlan accordingly in alignment with the specifications.

Connecting relevant metrics, vPlan features

Once the vPlan is defined, it’s important to connect the relevant metrics to demonstrate verification assurance of each feature. It may involve using a combination of code coverage, functional coverage, or directed test to provide that assurance. The Planning Center makes connecting these metrics to the vPlan very straightforward. Failing to link these metrics with the features could result in insufficiently verified features.

Showing real-time results

To effectively monitor progress and respond promptly to areas requiring attention, the vPlan should dynamically reflect the results in real time. This allows for accurate measurement of progress and focused allocation of resources. Delayed results could lead to wasted project time in non-priority areas. Verisium Manager’s vPlan Analysis automates this process enabling users to view real-time vPlan status for relevant regressions.

Customers have shared that vPlan quality significantly influences project outcomes. It’s crucial to prioritize creating higher quality vPlans, rather than simply focusing on speed. However, maintaining consistent high quality can be challenging due to the human tendency to quickly lose interest, with initial strong efforts tapering off as the process continues.

A thorough verification plan is the key to success in ASIC verification. Verification reuse is critical to the productivity and efficiency of system-on-chip (SoC), and a good vPlan is the first step in this direction. If you’re a verification engineer, take the time to develop a thorough verification plan for your next project. It will be one of the best investments you can make in the success of your project.
