In addition,You can find some details through the TI.com documents and the TI Wiki Pages.
Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics.
TI provides PCB layout specifications in the device datasheets for the following interfaces, eliminating the need to perform electrical analysis:
- DDR
- SATA
- USB
Note:
Make sure to follow the Layout Specifications for the Critical Interfaces like SATA - Refer the datasheet.
The below wiki articles might be help for SATA design
