+**Tasks:** Implementing the ALU chips in HDL.
 **Blocker:** Time and understanding.
 **Lesson:** Learned about some HDL syntax. Also the FullAdder, Add16 and Increment16. Got all of them. Was struggling with the Increment due to the syntax. I had the right idea.
 **Tomorrow:** Building the ALU chip from all the building blocks. Looking forwart to it.
