When I m migrating from Arria II GX device to Arria V GZ FPGA I m facing these errors . Please suggest me how to go about it .

Error (14566): Could not place 1 periphery component(s) due to conflicts with existing constraints (1 LVDS clock tree(s))

Error (175001): Could not place 1 LVDS clock tree

Info (14596): Information about the failing component(s):

Info (175028): The LVDS clock tree name(s): IO_MISC:INST_IO_MISC|arriavgz_pll_lvds_output_inst~quadrant

Error (16234): No legal location could be found out of 4 considered location(s). Reasons why each location could not be used are summarized below:

Error (175006): Could not find path between the LVDS clock tree and destination pin

Info (175027): Destination: pin iP48_RX_DIN[3]

Info (175015): The I/O pad iP48_RX_DIN[3] is constrained to the location PIN_E21 due to: User Location Constraints (PIN_E21)

Info (14709): The constrained I/O pad is contained within this pin

Error (175022): The LVDS clock tree could not be placed in any location to satisfy its connectivity requirements

Info (175021): The pin was placed in location pin containing PIN_E21

Info (175029): 3 locations affected

Info (175029): LVDS_CLK_TREE_X1_Y0_N1

Info (175029): LVDS_CLK_TREE_X1_Y88_N1

Info (175029): LVDS_CLK_TREE_X81_Y0_N0

Error (175006): Could not find path between the LVDS clock tree and destination pin

Info (175027): Destination: pin oS192_SFI_CLKOUT

Info (175015): The I/O pad oS192_SFI_CLKOUT is constrained to the location PIN_AF6 due to: User Location Constraints (PIN_AF6)

Info (14709): The constrained I/O pad is contained within this pin

Error (175022): The LVDS clock tree could not be placed in any location to satisfy its connectivity requirements

Info (175021): The pin was placed in location pin containing PIN_AF6

Info (175029): 1 location affected

Info (175029): LVDS_CLK_TREE_X81_Y88_N0

Error (12289): An error occurred while applying the periphery constraints. Review the offending constraints and rerun the Fitter.

Error (11802): Can't fit design in device

Error: Quartus II 64-Bit Fitter was unsuccessful. 9 errors, 10 warnings

Error: Peak virtual memory: 2974 megabytes

Error: Processing ended: Wed Mar 13 01:29:39 2019

It looks as though you have inappropriate constraints carried over from your original Arria II project. Remove all your old user constraints and then compile the design. Once you have the design compiled add pin and other constraints as necessary.

 

Cheers,
