I am working with cyclone v fpga(5CEBA2F23C8) .While running it i got the below problems.
Error (14566): The Fitter cannot place 1 periphery component(s) due to conflicts with existing constraints (1 PLL LVDS output(s)). Fix the errors described in the submessages, and then rerun the Fitter. The Intel FPGA Knowledge Database may also contain articles with information on how to resolve this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number.
Error (175001): The Fitter cannot place 1 PLL LVDS output.
Info (14596): Information about the failing component(s):
Info (175028): The PLL LVDS output name(s): lvdse:lvdse_inst|altlvds_rx:ALTLVDS_RX_component|lvdse_lvds_rx:auto_generated|pll_ena~PLL_LVDS_OUTPUT
Error (16234): No legal location could be found out of 8 considered location(s). Reasons why each location could not be used are summarized below:
Error (175006): Could not find path between source fractional PLL and the PLL LVDS output
Info (175026): Source: fractional PLL lvdse:lvdse_inst|altlvds_rx:ALTLVDS_RX_component|lvdse_lvds_rx:auto_generated|pll_sclk~FRACTIONAL_PLL
Info (175021): The fractional PLL was placed in location FRACTIONALPLL_X0_Y1_N0
Error (175022): The PLL LVDS output could not be placed in any location to satisfy its connectivity requirements
Info (175029): 4 locations affected
Info (175029): PLLLVDSOUTPUT_X0_Y38_N2
Info (175029): PLLLVDSOUTPUT_X0_Y39_N2
Info (175029): PLLLVDSOUTPUT_X54_Y38_N2
Info (175029): PLLLVDSOUTPUT_X54_Y39_N2
Error (175006): Could not find path between the PLL LVDS output and destination pin
Info (175027): Destination: pin lvdse_in[0]
Info (175015): The I/O pad lvdse_in[0] is constrained to the location PIN_G6 due to: User Location Constraints (PIN_G6)
Info (14709): The constrained I/O pad is contained within this pin
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_G6
Info (175029): 4 locations affected
Info (175029): PLLLVDSOUTPUT_X0_Y1_N2
Info (175029): PLLLVDSOUTPUT_X0_Y2_N2
Info (175029): PLLLVDSOUTPUT_X54_Y1_N2
Info (175029): PLLLVDSOUTPUT_X54_Y2_N2
Error (12289): An error occurred while applying the periphery constraints. Review the offending constraints and rerun the Fitter.
