Swizzle Bus Pin Assignment Example
This file contains the implementation of a simple example
of the swizzle-bus pin assignment tool. The idea is that
given a bus of signals, we want to allow the pin assignment
solver to determine the right order of pins to use. This is a
common tactic in DDR3 busses where the byte lane pins can
be in any permutation of the pins.
Additionally, the swizzle-bus function has a locked argument
that allows the user to restrict the set of pins in the bus that
are allowed to swizzle. For example, some chips require the first
and/or last pin of the byte lane to be locked.
