Introduction

...

• For complex ICs, do NOT match IC pinouts to their physical layout. Instead, put power pins on top, ground on the bottom, inputs on the left and outputs on the right. See here for reasoning.
• Component Naming Convention
  • IC/CAP/RES/EVAL/CONN/LED/IND/MOSFET/POT/DIODE/CRYSTAL/XFMR DESCRIPTION(S) PACKAGE(If applicable)
• Align all pins to a 10mil snap grid (Basic Concepts - Grids).
• Use pin length of 20mil.
• Add Component Parameters using the Supplier Search feature (Libraries and Component Creation - Using Supplier Search to add Component Parameters in Bulk)
• Set important parameters to visible so they can be viewed in the schematic:
  • Capacitors (Capacitance, Voltage, Temperature Coefficient)
  • Resistors (Resistance, Power, Tolerance)
  • Inductors (Inductance)
  • Connectors (Pitch)
  • Crystals (Frequency)
  • Diodes (Voltage, Current (for Schottky Diodes), Power (For TVS Diodes))
  • LEDs (Forward Voltage, Colour)
  • Complex ICs (Manufacturer Part Number)
  • Other (Relevant maximum ratings as necessary)
