1. From the user point of view, place and route are often
lumped together as necessary physical operations.
From an algorithm point of view, placement and routing
are very different.
2. Routing is the blue-collar work of IC design.
There are no conceptual difficulties and very little
use of higher mathematics.
The success of a router is determined by hard work,
heuristics, and implementation.
3.
Almost all state-of-the-art routers are built in
industry, and relatively little is published about them.
In contrast, the placement problem can be attacked using
a wide variety of techniques, some quite sophisticated,
and many academic groups develop their own placers.
4. A placement contest at ISPD in 2005, using state-of-the-art
examples, drew nine contestants from academia.
A similar contest for routing would probably not find even
one academic router that can solve a state-of-the-art routing
problem.
