Why is the tRTP timing parameter box missing from the Intel® Stratix® 10 and Intel Arria® 10 EMIF IP GUIs?


The tWR and tRTP parameters share the same DDR4 MR0 mode register bits.  Once the tWR parameter is set, the tRTP parameter is set automatically because the tWR and the tRTP relationship is fixed.
