How do I set the timing parameters for DDR3L?

Description

Some of the timing parameters in the manufacturers' DDR3L SDRAM datasheets may not be defined, but you can refer to the DDR3 SDRAM datasheet to use the timing parameters for the MegaWizard™ settings. DDR3L SDRAM (1.35V) is a low voltage version of the DDR3 SDRAM (1.5V).

Unless stated otherwise, DDR3L SDRAM meets the functional and timing specifications listed in the datasheet of the equivalent density DDR3 SDRAM. The recommended flow is to refer to the DDR3 SDRAM datasheet for any timing parameters not specified in the DDR3L datasheet.
