How AI And Connected Workflows Will Close The Verification Bottleneck

The industry needs a fundamental shift in how verification is approached.

popularity

For decades, verification has been the unsung hero of chip development—quietly catching bugs before they reach silicon. But as semiconductor complexity has skyrocketed, verification has turned into the bottleneck of development cycles.

This challenge has a name: Verification Productivity Gap 2.0.

Back in the early 2000s, the Verification Productivity Gap 1.0 emerged when design complexity outpaced traditional verification methods, leading to longer schedules and higher costs. The industry responded with constrained-random verification, coverage-driven methodologies, and formal verification, which helped stabilize the gap to some extent as design complexity increased.

Fast forward to today, and we’re facing Verification Productivity Gap 2.0, driven by 3D ICs, chiplet-based designs, and software-defined architectures. These innovations bring new challenges:

  • Multi-die and multi-domain interdependencies that require verification across previously isolated domains.
  • Hardware/software co-verification challenges as firmware increasingly defines system functionality.
  • Exponential growth in verification complexity, making traditional coverage models infeasible.

The result? Verification cycles are now growing faster than design cycles. Engineering teams are spending more time debugging, running regressions, and managing verification complexity—leading to schedule delays, cost overruns, and silicon respins.

According to the “2024 Siemens EDA and Wilson Research Group Functional Verification Study”, only 14% of ASIC projects achieve first-silicon success—the lowest rate ever recorded. FPGA projects fare no better, with just 13% avoiding major bug escapes in production.

The industry needs a fundamental shift in how verification is approached. The solution? AI-powered, connected verification workflows that eliminate inefficiencies and optimize engineering resources.

Why disconnected verification is holding teams back

Traditionally, verification has relied on a collection of point tools, each focused on a specific task—simulation, formal, emulation, prototyping—often operating in silos.

This disconnected approach leads to:

  • Redundant testing across tools, wasting valuable simulation and emulation resources.
  • Slow, manual debugging across domains, with engineers spending more time triaging failures than improving coverage.
  • Fragmented coverage visibility, allowing bugs to slip through because insights from different verification methods aren’t shared efficiently.

Disconnected workflows force verification teams to manually stitch together data, slowing progress and increasing risk. These inefficiencies are widening the Verification Productivity Gap 2.0, and traditional methods simply can’t keep up.

The solution isn’t just adding more engineers or compute power. The key is smarter, more connected verification.

How AI and connected workflows are changing the game

The semiconductor industry is on the brink of a major transformation. While AI-driven verification and connected workflows are still in their early stages, preliminary results from early adopters show significant benefits in reducing verification cycles, improving coverage, and speeding up debugging.

Engineering teams adopting AI-powered test automation, predictive analytics, and cross-domain verification platforms are reporting these advantages:

  • Identifying bugs earlier, reducing the likelihood of expensive late-stage fixes.
  • Optimizing test execution, achieving similar or better coverage with fewer cycles.
  • Shortening debug cycles, with AI-assisted triage surfacing failure patterns more quickly.

Though broad adoption is still evolving, these early successes suggest that companies effectively adopting AI and connected verification strategies will produce next-generation chips more quickly, with fewer respins, and at reduced costs.

AI-driven verification: Intelligence meets optimization

AI-powered tools are proving invaluable in:

  • Smart test generation: AI can analyze existing coverage gaps and propose optimized test cases, especially in hard-to-reach scenarios.
  • Predictive analytics for regression testing: AI helps teams intelligently prioritize test runs, reducing the need for exhaustive simulations.
  • AI-assisted debugging: Early adopters report that AI-powered tools are accelerating root cause analysis, helping engineers diagnose failures in minutes instead of hours or days.

Connected verification: Eliminating tool silos

Disconnected verification tools have long been a pain point in the industry. Early adopters of connected verification workflows—which unify simulation, emulation, and hardware/software co-verification—are already seeing:

  • Faster test execution, as teams avoid redundant runs across separate tools.
  • Improved first-silicon success rates, by catching cross-domain failures earlier.
  • Real-time sharing of verification insights, reducing costly misalignment between design and verification teams.

By shifting toward AI-enhanced, connected verification, companies can position themselves ahead of the curve, mitigating the risks posed by Verification Productivity Gap 2.0 while gaining efficiency and cost advantages.

The ROI of smarter, connected verification

For engineering directors and technical leads, AI-driven and connected verification isn’t just a theoretical improvement—it’s a business necessity.

Why smarter verification matters

Silicon respins cost millions. A single respin at advanced nodes can cost over $10M in fabrication expenses alone. Every bug caught pre-silicon saves massive downstream costs.

  • First-silicon success: Faster time-to-market delivers a higher competitive advantage and accelerates revenue.
  • Engineering productivity gains: AI-assisted debugging significantly reduces manual debugging efforts, freeing up engineers for higher-value tasks.
  • Compute efficiency: Smarter test selection and predictive regressions reduce wasted simulations, lowering compute costs.

By integrating AI and connected verification, engineering teams can shorten schedules, improve quality, and optimize resources—driving measurable improvements in time-to-market and cost savings.

Final thoughts: The future of verification is connected

The Verification Productivity Gap 2.0 is a reality that the semiconductor industry must address head-on. Design complexity isn’t slowing down, and disconnected verification workflows are no longer sustainable.

By embracing AI, automation, and connected verification, engineering teams can transform verification from a bottleneck into a strategic advantage.
