About this listen

 Every chip has bugs — the real question is how fast you can find and fix them. Bugged Out is the bite-sized podcast where we shine a light on the art (and science) of functional verification. In just 10–15 minutes per episode, host Harry Foster, Chief Scientist, Verification, Siemens EDA, sits down with leading innovators, engineers, and researchers to talk about what’s shaping the future of verification — from AI-driven tools to design-for-test, coverage closure, reliability, and more. Expect candid conversations, practical insights, and a few “war stories” from the trenches of debug. Whether you’re a verification engineer, a design lead, or simply curious about how we “get the bugs out” of the chips that power our world, Bugged Out delivers focused, informative conversations designed to fit your busy schedule.Siemens Digital Industries Software

  • SDC verification as a first-class asset: A deep dive with Chandu Challapalli

    SDC verification as a first-class asset: A deep dive with Chandu Challapalli
    Jan 27 2026
    In this episode of Bugged Out, Harry Foster talks with Chandu Challapalli, Senior Management Director at Siemens EDA, about why timing constraints must be treated as first-class verification assets. Drawing on insights from his white paper, A Guide to SDC-Based Timing-Intent Verification with Questa One, Chandu explains how automated SDC verification uncovers hidden timing risks, balances under- and over-constraining, and shifts timing validation earlier in the design cycle. Learn how Questa One brings structure and automation to timing-intent verification—helping teams achieve faster signoff and greater confidence in first-pass silicon success. Key Discussion Points Why Timing Constraints Matter: How SDC files capture design intent—and why ignoring their verification invites silicon risk. What Is Timing-Intent Verification?: A clear explanation of validating clocks, exceptions, and constraints against real design behavior. Finding the Right Balance: The hidden costs of under-constraining versus over-constraining timing. Common SDC Pitfalls: Missing clocks, invalid exceptions, and legacy constraints that mask real bugs. Shifting Left on Timing: Why verifying constraints early—alongside RTL—reduces late-stage surprises. What’s Next: A glimpse into continuous, AI-assisted timing-intent verification and tighter frontend/backend alignment.

    FutureCast 2026 — Part 1: When silicon becomes a living system
    Dec 9 2025
    Join host Harry Foster for a special holiday edition of Bugged Out. In this first episode of the two-part FutureCast 2026 series, Harry steps away from the usual guest interviews to look at how the semiconductor industry is evolving — and why innovation is now happening far above the transistor. This episode explores why modern silicon behaves less like a static product and more like a living, continuously changing system. Harry highlights the technologies driving this shift, from multi-die architectures to software-defined hardware, and explains how verification must expand across the entire product lifecycle. Key discussion points: Why innovation has moved above the transistor How chiplets, hybrid bonding, and HBM are redefining system performance The collapse of traditional design boundaries across logic, timing, thermals, and software Emerging system-level behaviors in multi-die architectures Why these changes reshape verification across physical and logical domains The role of hybrid digital twins in capturing system truth How software-defined products evolve after shipping Why OTA updates become verification events The shift from traditional to lifecycle-aware verification Predictions for 2026: multi-die verification becomes essential, and lifecycle-aware verification becomes mandatory for advanced AI-driven devices Predictions for 2030: hybrid digital twins become foundational, and early chiplet vendors enter the market with curated offerings
