Does SSTL15 pin needs pull up resistor in KC705?

Jump to solution
DDR3 module exsits in K705. The address and control pins of ddr3 module are connected to HP bank using sstl15 standard. According to Figure 1-57 (page 78)in 7 series FPGAs selectIO resources user guide, there should be pullup resistor on both the FPGA and DDR3 side. DDR3 may have ODT instead. however, SSTL15 is not a DCI mode and therefore should be a pullup at the FPGA side.KC705 does not have pull up resistor on both side. Why?
