In a traditional full-custom ASIC design flow, the next step would be the laborious, expensive, and error-prone process of manual transistor layout required to translate the design to silicon.

However, full custom power management ASIC development historically has been expensive, slow-to-market, and pretty risky.

New adapter USES the created by company custom-made microcircuit (ASIC) whereas, previously Sun bought 10 gigabit controllers in S2IO.
