VISTAR™: The AI Platform Redefining Semiconductor Product Development

In an industry where innovation is measured in nanometers and deadlines leave no room for delay, semiconductor companies are facing pressure like never before.

AI is no longer a luxury, it’s the new baseline.

From leading EDA vendors like Synopsys and Cadence to agile startups, AI is being embedded deep into workflows, automating design, verification, testing, and more. But deploying AI in a high-stakes, IP-sensitive industry like semiconductors comes with serious trade-offs.

That’s exactly the problem SilTest set out to solve.

Introducing VISTAR™: Built for Engineers, Not Generalists

VISTAR™ :(Virtual Intelligence System for Task & Agent Regulation) is SilTest’s proprietary AI platform, engineered specifically for semiconductor workflows.

Unlike public AI models or generic tools, VISTAR™ understands the nuances of chip design, test development, and yield analysis. It’s modular, secure, and deeply customizable, delivering AI that works the way engineers think.

Why Generic AI Tools Fail in Semiconductor Workflows

It’s tempting to use open-source or public chatbots like ChatGPT, Gemini, or Claude for technical tasks. But in semiconductor environments, these tools fall short in critical areas:

• IP Leakage & Legal Risk: Prompts and data might be used for model training or shared externally.

• Data Residency Uncertainty: No control over where your data goes or who sees it.

• Lack of Domain Understanding: These models don’t grasp semiconductor-specific terminology, test protocols, or design flows.

• No Contextual Memory: They can’t follow multi-step technical operations with traceability or auditability.

This leaves teams exposed and makes the “free” solution far more costly in the long run.

The Myth of Building AI In-House

Some companies assume building their own AI stack internally will offer more control. But that often results in a half-finished MVP that consumes massive resources without delivering scalable outcomes.

Here’s how internal efforts compare to VISTAR™ :

How VISTAR Works: An AI Engine Tuned for Semiconductors

At the core of VISTAR™ is a flexible, scalable architecture with multiple LLM cores, a policy engine, secure orchestration layer, and patented modules to handle multimodal inputs (documents, logs, test data, etc.).

Key Features:

• Multimodal AI Engine: Handles DOCX, CSV, STDF, emails, logs, PDFs, and more.

• LLM Orchestration Engine: Seamlessly manages multiple AI models to execute workflows.

• Data Structuring: Transforms raw inputs into clean, queryable formats automatically.

• Agentic Planning Interface: Supports multi-step tasks with little input.

• Enterprise-Grade Security: RBAC/ABAC access control, prompt-level safety layer, and complete on-premise compatibility.

• Admin Dashboard: Full visibility over cost, performance, behavior, and rights.

• Built-in AI Agents: Tailored to yield, test, DFT, root-cause analysis, document creation, and more.

Real-World Results: 50–80% Productivity Gains

In live deployments, VISTAR™ users reported:

• Significant time savings in documentation, test debugging, and analysis

• Better decisions through AI-powered insights and smart agents

• Reduced errors in test planning and yield prediction

• Shorter meetings thanks to automated knowledge assistants

Specialized Modules for Targeted Results

VISTAR™ comes with plug-and-play modules that can be tailored to different departments or goals:

• DemandSynX – For market and supply chain insights

• DeepSpeX – AI-powered spec generation from architecture docs

• SightFiX – Hardware failure analysis and pattern detection

• YieldOptiX Pro – Advanced yield analysis, automated reporting

The Bottom Line

VISTAR™ offers more than automation, it’s a paradigm shift in how semiconductor teams think, plan, and execute.

It's secure. It’s fast. And it’s built by people who speak the language of silicon.
