compilation of design with DDR2 controller in startix IV fails

HI,

When I'm trying to compile ddr2 controller to STRATIX IV with quartus 10.1 , I got the following errors, does anyone know how to overcome them ?

Error: Termination calibration block atom "dbm2ddr2_control: control|control_0002: control_inst|control_0002_controller_phy:controller_phy_inst|control_0002_memphy_top:memphy_top_inst|control_0002_oct_control:uoct_control|sd1a_0" uses RUP port, which must be connected to an I/O atom in input mode File: control_0002_oct_control.v Line: 82

Error: Termination calibration block atom " control: control|control_0002:control_inst|control_0002_controller_phy:controller_phy_inst|control_0002_memphy_top:memphy_top_inst|control_0002_oct_control:uoct_control|sd1a_0" uses RUP port, which must be connected to a dedicated I/O atom with no other fanout File: control_0002_oct_control.v Line: 82

thanks in advance,

    it looks like you don't have the RUP RDN ports of the memory controller connected all the way out to pins
