Electrical

• Do not draw power and ground pins. That information will be conveyed using attributes (see the netattrib document).
• The above rule can be broken if necessary, but keep in mind most of the standard library does not have power pins showing.
• Keep in mind, symbols are supposed to be symbolic, they do not represent the physical package that the device comes in.
• There is some disagreement on above, so this is okay too: Arrange the pins on a symbol logically so that they promote an uncluttered schematic. Note that this is frequently not the same pin arrangement as the physical device.
