Harmonic Expands Aristotle to C and Verilog After Raising $295 Million

2 articles · Updated · WIRED · Oct 29

Summary

  • Harmonic said this week its AI agent Aristotle can now verify software written in C and hardware designs in Verilog, widening its push to automate formal verification.
  • The move comes as startups argue generative AI can slash verification costs and timelines—Stanford researcher Chuyue Sun reported one project finished in under half a day for less than $500, versus five months by three experts.
  • Harmonic is testing Aristotle with potential users including Tensordyne and Nvidia, whose venture arm backs the company, while rival &Truth launched publicly after raising $70 million.
  • Formal verification already protects security-critical code in systems from Boeing planes to more than 2.5 billion Apple devices, but adoption remains limited by scarce specialists, high costs, and fears of slowing software releases.
  • Skeptics say mathematically verified code can still miss failures tied to user behavior or hardware, leaving open whether AI can push the technique beyond niche, high-stakes systems.

Insights

As &Truth and Harmonic raise huge funding, can AI-checked proofs beat traditional testing for real-world software and hardware security?
If AI can verify encryption code in hours for under $500, what still prevents formal verification from becoming standard software practice?
Did Chuyue Sun’s Signal-related breakthrough solve formal verification’s biggest bottleneck—or just move the trust problem to specifications and proof tools?
