Option Expression

Option expressions are used on logical schematics to define required variations in connectivity. They are calculated for wiring after synthesis and define variations in wiring content.

They are a combination of option (or variant option) codes, defined using boolean operators AND (intersection) and OR (union) together with NOT (negation).

The binary operators used are:

&& = AND

|| = OR

! = NOT (can be combined with either AND or OR)

An example is LHD && ABS indicating an object required only in a left-hand drive vehicle containing the anti-lock braking system.
