Stick diagrams help plan layout quickly
Ø Need not be to scale
Ø Draw with color pencils or dry-erase markers
Wiring Tracks
A wiring track is the space required for a wire
· 4 λ width, 4 λ spacing from neighbor = 8 λ pitch
Transistors also consume one wiring track
Well spacing
Wells must surround transistors by 6 λ
Implies 12 λ between opposite transistor flavors
Leaves room for one wire track
Area Estimation
Ø Estimate area by counting wiring tracks
Ø Multiply by 8 to express in λ
