Samsung reduces mobile chip development time to days with Claude Code

Summary

Samsung's System LSI division reported using Anthropic's Claude Code tool for approximately three months. The company claims that a specific SoC verification task, which normally takes over a month, was completed in two days, achieving up to a 15x speedup in some critical processes. Samsung positions this step as a way to close the capability gap with Qualcomm, which has over 52,000 engineers compared to Samsung's 6,000. The company is also integrating Gemini and ChatGPT in other divisions.

Why it matters

Mobile SoC design is one of the most capital- and time-intensive engineering fields in the tech industry. Therefore, even small reductions in cycle times can alter the competitive dynamics between Samsung's Exynos series and Qualcomm's Snapdragon series. If AI-assisted verification truly compresses months of RTL and datapath work into days, it could reshape how semiconductor teams staff projects and how quickly they complete design iterations. The broader picture shows that frontier coding models are moving far beyond software into hardware verification workflows, where the cost of errors is significantly higher.

Highlights

• A missing RTL file was replaced with virtual blocks generated by Claude Code. Full data structure verification was completed in two days, compared to the usual duration of over a month.
• An engineer with no prior experience with Claude Code built and verified keyboard and mouse simulation models in one day. Samsung notes that this task normally takes over a month.
• Claude Code produced real errors, including modifying irrelevant code and reverting completed work. As a result, every action requires human approval before being accepted.

Critical take

The headline claim of '15x speedup' relies on a single anecdotal SoC verification case and vague qualifiers like 'some critical processes,' making it difficult to generalize across a 6,000-person chip team. Furthermore, engineers must review every AI action before approval. This implies that actual wall-clock time savings may be smaller than the raw production time figures suggest. In the context of hardware design, a code assistant that still makes errors does not close the engineer headcount gap with Qualcomm.
