There is a lot more great content on the HashFast blog that somehow escaped the forum's notice!

These are screenshots of the CGminer software output.
CG Miner is one of the standard mining software packages that can interface with either CPU, GPU or ASIC (Application Specific Integrated Circuit) mining equipment.
Here, it is integrated with our own driver for the HashFast ASIC, and is connected to a HashFast core running inside an FPGA (Field Programmable Gate Array ), simulating the same logic that our ASIC is running. The following images show a demonstration of that ASIC logic actually running against BTC Guild and mining bitcoins.
