Cost Estimates
NRE (Non-Recurring Engineering): This includes design, verification, mask creation, and initial test runs. For a mature node like 28nm, NRE can range from $5–8 million for a moderately complex design, possibly exceeding $15 million if the design is very intricate. For advanced nodes (7nm/5nm), NRE can go beyond $20–30 million.
Per-Wafer Costs: Once the mask set is completed, the cost per wafer varies by node. At 28nm, each wafer might be a few thousand dollars, while at 7nm it could be between $10,000 and $15,000 per wafer. Final unit cost depends heavily on volume and yield.

Finally, a concrete proposal for building an ASIC running the Kangaroo algorithm. The challenge, as expected, is the cost. Unless there’s serious financial backing or a strong business case, it’s a massive investment for a niche application.
