    I remember seeing a similar error. Try copying the following TCL files into the build directory(Where the QPF file is located).

    <Project name>_phy_autodetectedpins.tcl

    <Project name>_Controller_phy_ddr_pins.tcl

    <Project name>_Controller_phy_ddr_timing.tcl

    <Project name>_Controller_phy_report_timing_core.tcl

    I think this will get rid of the errors.
