Database commands: append

Syntax: append deffile1 deffile2

This will copy the DEF file deffile1, while adding the physical routing information, to deffile2. This is pretty much the same as the Qrouter output method. The deffile1 must be the original input DEF file, or contain the same instance placements and abstract routes. When the router is run, the physical routes are written back to the database, where they can be used to update the original source as described.
