  Understanding TI's PCB Routing Rule-Based DDR Timing Specification (Rev. A)
  PDF, 93 Kb, Revision: A, File published: Jul 17, 2008
  This application report motivates the way the DDR high-speed timing requirements are now going to be communicated to system designers. The traditional method of using data sheet parameters and simulation models is tedious. The system designer uses this information to evaluate whether timing specifications are met and can be expected to operate reliably.Ultimately, the real question the hardwa
