fitter error for conflitcs in constraints.

[PShar32]

hi,

    I am trying to modify the, GHRD for my cyclone V DE1 soc,  i added few pios and nios 2 processors to the GHRD using qsys. Quartus is able to do analysis and synthesis, but it is giving out an fitting error.

Error (14566): The Fitter cannot place 10 periphery component(s) due to conflicts with existing constraints (

1 HPS_INTERFACE_HPS2FPGA(s),

1 HPS_INTERFACE_HPS2FPGA_LIGHT_WEIGHT(s),

1 HPS_INTERFACE_PERIPHERAL_SPI_MASTER(s),

1 HPS_INTERFACE_INTERRUPTS(s),

1 HPS_INTERFACE_CLOCKS_RESETS(s),

1 HPS_INTERFACE_FPGA2HPS(s),

1 HPS_INTERFACE_TPIU_TRACE(s),

1 HPS_INTERFACE_DBG_APB(s),

1 HPS_INTERFACE_BOOT_FROM_FPGA(s),

1 HPS_INTERFACE_FPGA2SDRAM(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.

please help me with the reason of this error and how it can be solved.

regards

Can you attach your qsys for the modified GHRD ? are you booting from fpga?
