Episode notes
Softgo and TSMC
- Huawei used a shell company, Softgo, to purchase chips from TSMC, circumventing the initial restrictions.
- TSMC's implementation of the "red flag" guidance was inadequate, allowing Softgo to operate undetected.
Technical Challenges in Chip Identification
- Distinguishing advanced AI chips from less strategically important ones presents a technical challenge.
- TSMC cannot accurately calculate a chip's processing power (flops) before fabrication, making preemptive control difficult.
Revised Red Flag Guidance
- The red flag guidance now uses transistor count as a proxy, requiring TSMC to perform technical estimates.
- This addresses the issue of companies like Softgo misrepresenting chip specifications.
