Puzzle 10 of 100

Four equal steps

Goal

Make Y read 3.75 V, Z read 2.5 V, and W read 1.25 V: the supply divided into four equal steps.

Die: 10 by 15 squares
Layers: Metal, Polysilicon, Contact
Outputs: Y, Z, W
Supply: VDD
Ground: GND

Hint

Run one polysilicon strip from VDD to GND and place a contact for each output along it, with the same number of squares between every pair of neighboring contacts.

About the drawing

The drawing uses 36 of the die's 150 squares.
The die starts empty, so you draw every square.
5 contacts join metal to the polysilicon or active silicon under it.
