CHIP DESIGN'S REAL AI BOTTLENECK ISN'T INDIVIDUAL TOOLS, IT'S WHAT HAPPENS BETWEEN THEM

Summary from the TLDR Hardware newsletter

Semiconductor design spans dozens of specialized tools - RTL, synthesis, place-and-route, timing sign-off, and DFT - each written by a different vendor with different assumptions about what "done" means. Every handoff between tools risks silently losing design intent, a problem serious enough that first-time silicon success has fallen sharply, with most respins still traced to these intent-transfer failures rather than raw errors. The consensus emerging is "evidence-driven automation": AI can propose fixes, extract properties, and orchestrate handoffs between agents, but every output has to remain independently checkable through formal proof, deterministic verification, and audit trails, since an AI-generated assertion is a hypothesis, not proof, until it's checked against a real engine.
