Source Synchronous Timing

This document goes into detail on how to constrain source-synchronous interfaces. It is a follow-on to the TimeQuest User Guide:

The document starts off with a standardized approach to constraining source-synchronous interfaces, called the Explicit Clock Method.  This easy-to-understand method works whether the FPGA is the receiver or transmitter, and if the interfaces are center-aligned or edge-aligned.  

Next is a section on the Implicit Clock Method, which I consider to be purely optional. 

There is a section called Miscellaneous, which covers many of the details and points of confusion for source-synchronous DDR interfaces. 

Finally are the examples. There are some generic examples(without projects) as well as analysis of four Texas Instrument devices interfacing to an FPGA.
