Rules are given in order of priority.

• Consistency is key for clarity

  • a single schematic should follow the same styling conventions

• passives to power rails should be vertical

  • i.e. i2c pullups and decoupling capacitors

• schematics should follow a logical left to right flow

  • input on the left, output on the right

• higher electrical potential (voltage) rails should be above lower voltage rails

• signal passives should be horizontal.

  e. shunt resistors

• Show Parameters for components

  • it should be obvious which parameter corresponds to which component based on proximity.

• minimize corners in schematic wires when possible

• components should be placed in the schematic near components they will be near in the layout when sensible

  • notably, decoupling capacitors should be placed in the schem near the IC they’re decoupling rather than say off on a random sheet. See https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2178154501/Decoupling+Capacitors?search_id=be08defc-9cba-48a6-9283-64e3f906590c&additional_analytics=queryHash---0f1c3fed2128d86a807147c6bab7604e287482b1998d87d9ba440968c2c77c3f for further detail.

• minimize length in schematic wires when sensible

• do not use excessive hierarchy

  • do not have a bunch of nested schematic sheets, it makes things confusingexcessively nest schematic sheets

• minimize intersecting schematic wires when sensible

Why We do this

• Standard

  • Makes makes reviews easier !

  • Improves improves human readability

  We dont

  • preparation for industry

• We don't want to nitpick

  • If you have a reason for doing something slightly different it’s fine

  • there are a lot of edge cases these simple guidelines dont don't cover so do what’s best and call it a day

    • as long as you did something for a reason then it’s chill, just don’t do things randomly

    • do not do styling randomly/arbitrarily

Learning

The best way to learn is to look at schematics and see what you think is reasonable. Check out past WARG designs and see how they style their schematics. Not everything we do is perfect, but a lot of it is decent and a great starting place!
