ID:18116 CLKUSR pin cannot be used for both calibration and device initialization. Use the INTOSC (Internal Oscillator) or DCLK for device initialization using the global assignment 'set_global_assignment -name DEVICE_INITIALIZATION_CLOCK <INIT_DCLK or INIT_INTOSC>'.

CAUSE: The design has transcievers or certain IOs and CLKUSR pin is used for their calibration. There also exists a global QSF assignment specifying CLKUSR to be used for device inititalization. CLKUSR pin cannot be used for both transciever calibration and device initialization.

ACTION: Use the DCLK or INTOSC (Internal Oscillator) for device initialization using the global QSF assignment 'set_global_assignment -name DEVICE_INITIALIZATION_CLOCK <INIT_DCLK or INIT_INTOSC>'.
