Error HSMC in Standard differential host pinout on the Arrow SoCkit

[Altera_Forum]

Hi all, 

I'm starting a new project with the Arrow SoCkit, in which I want to use the LVDS pair of the HSMC at the maximum speed. The pin out of the project is the Arrow SoCkit pinout, but when I implement the pll and the LVDS RX/TX quartus gives to me this error:   Error (175006): Could not find path between the PLL LVDS output and destination pin  Info (175027): Destination: pin hsmc_tx_p[0]  Info (175015): The I/O pad is constrained to the location PIN_A9 due to: User Location Constraints (PIN_A9)  Error (175022): The PLL LVDS output could not be placed in any location to satisfy its connectivity requirements  Info (175021): The pin was placed in location pin containing PIN_A9  Info (175029): 10 locations affected  Info (175029): PLLLVDSOUTPUT_X0_Y1_N2  Info (175029): PLLLVDSOUTPUT_X0_Y2_N2  Info (175029): PLLLVDSOUTPUT_X0_Y15_N2  Info (175029): PLLLVDSOUTPUT_X0_Y16_N2  Info (175029): PLLLVDSOUTPUT_X0_Y32_N2  Info (175029): PLLLVDSOUTPUT_X0_Y33_N2  Info (175029): PLLLVDSOUTPUT_X0_Y56_N2  Info (175029): PLLLVDSOUTPUT_X0_Y57_N2  Info (175029): PLLLVDSOUTPUT_X89_Y1_N2  Info (175029): PLLLVDSOUTPUT_X89_Y2_N2  Maybe I'm doing it wrong Can anyone help me?
