DDRSS Register Configuration Tool Updates
The DDR Register Configuration Tool provides custom register settings based on system level details such as the architecture (density, data width, ranks) of the DDR device, frequency of operation, and IO settings determined through board simulations. This tool may be updated over time to support new devices and/or features, fix issues identified with the tool, and most importantly, capture work-arounds of errata or recent updates identified to register calculations which improve performance, signal integrity, or timing relationships between signals.
In order to ensure that parameters are set appropriately based on lessons learned and reduce the risk of functional failure, the latest DDR register configuration tool should always be used to generate register values. As the DDR register configuration tool can periodically be updated, the revision history of the tool should be reviewed and evaluated whether tool changes apply to existing systems. When applicable, the configuration of an existing system should be updated appropriately. The latest version of the tool can be found at http://dev.ti.com/sysconfig, and choosing DDR Configuration under Software Product drop down for the applicable device that is being used.
