1. Sectioning

seperate to several shematic pages
add schematic page number and title
show connection between pages

/posts/schematic-tips-and-tricks/sectioning.png — good sectioning example

2. Title Block

/posts/schematic-tips-and-tricks/title-block.png — title block example

3. Text and Calculations

/posts/schematic-tips-and-tricks/text.png — text and calculations example

4. Symbols

create symbols that group input on the left, and output on the right (not actual pinout)
always let ground pad or something connect to ground facing down

5. Crossings

use cross-overs at the junction of two wires that is not connected to each other

6. Net Labels

Label all nets (useful in layout routing)

7. Horizontal Text

8. Power and Ground Direction

power all pointing up
ground all pointing down

9. Junctions

don’t make 4-bar junction, since node will show up even if there is no connection
use 3-bar junction instead

10. Don’t overlap Text

11. Component Order and Placement

place components in order of layout adjacency
decoupling capacitors should be placed close to the relavent power pins
for example, high frequency, smaller capacitance capacitors should be placed close to the power pins

12. Colors

helpful in layout routing

13. Annotation

every component in a page start with page number * 100
