How to Design an RTL Circuit with Basic Logic Components?

[mathrocks]

I have to design a circuit that does the following operations:

Add L to w w<--w+L
Increment w w<--w+1
arithimetic left shift w w<--arithemetic left shift of w
2's complement of w w<--w'+1
Bit-wise complement of w w<--w'
load L into w w<--L


How do I go about even starting to make this circuit using only inverter gates, NAND gates, 4 input multiplexers, D flip flops, and a 4bit adder.

There has to be some easy way through a simple truth table. My teacher likes to just draw the entire circuit out, but I can't see it that way.

Thank you!

There are several steps in the specifications. Just take them one step at a time in order, and couple the output of step 1 as the input to step 2. Presumably, the course has taught you how to do all those individual steps.
