Update
Our RTL design, optimization and simulation are finished. We have some data to predict the specification of actual chips after they are manufactured.
Hashrate: 1.25GH/s per chip
Area: 17.5mm^2 per chip
Power Consumption: 13.3W
Note that they are calculated from the front-end design and not accurate enough. But of course the possible difference range won't be large. We will keep our updates.
